98 Dash upgrade.

[siveradoss22s]

I just purchased my 98 silverado dash yesterday and will pick it up today. I got the whole complete dash with the exception of the stereo, ac controls, and passenger air bag...I got it for $185 (grey just like my interior.) He even threw in the ducts connected to the dash ac vents..

I guess I'll be using the same steering wheel for meanwhile. The My original AC controls (93) should relocate where the (98) controls were..As for the CD player, I have aftermarket so that is not a problem. The headlight switch shouldnt be much of a problem following diagrams.. I will start installation tomorrow early morning. Will take pics of steps as I progress.. I do need help if you all don't mind..

1. Wiring diagram for headlight switch conversion (93 to 98 style)
2. Wiring diagram for AC controls (93 to 98 style) if not Ill just keep original and relocate!
3. Im looking for a passenger airbag delete pocket.. ? Where can I get them? Or my thought were to just put my 6 inch widescreen monitor I have in my 93 dash where the original radio was and center it in there with fiberglass? Opinions?
4.Would it be too hard to change steering wheel and column?

Ill post up some pics tomorrow night.. but please, anyone who has done this conversion help out and Il do the same once I get started.. thanks

On the steering column,you can make the wiring all work if you are fairly competent with wiring schematics(you got the manuals for your truck,and the donor truck right?)The column does mount in a different location so some fabrication will be needed there.I have seen some people cut and splice the two columns,I chose to cut a section out of the firewall and move the mount.FYI I am swapping a full 96 power interior into my 92 along with the 96 vortec 350 and 4l60e.

[chevyz71man]

My advice for the heater controls is to follow the harness on the stock truck and take everything it connects to. Alot of the stuff is reversed in polarity and it is a pain in the butt. To many relays to much mess. For the headlight switches just uses a ohm reader to figure out what wire goes were. shouldnt take much effort. I dont have a ton of information on the swap because I am in the process of getting all my red interior parts still. I think getting the cluster to work will be my only hold up.

[BigBody90]

If you ever figure out how to convert the ac controls, let me know. I have done the conversion and didn't even want to try to figure out how to do the ac control swap. I am currently using the old one but the new one would look much better. I did wire up the new headlight controls, they were pretty easy. I didn't get eveything to work, like the dome override and the dimmer switch. If you ever get the dimmer function to work I would be interested.

last page of this thread has information on getting it to work http://www.fullsizechevy.com/forums/showthread.php?t=168825

on the headlight switch, which colors did you mate together?

[BigBody90]

I just checked my headlight wires and here is what I got.

yellow to yellow, red to red, green to green, orange to orange, brown to brown, black to brown

that was all pretty much straight forward

These are what I have left over on the new switch that I could not figure out.

Pink, Grey, White, Purple, Purple w/ white stripe

If anyone knows what these do please post a solution for me.
As far as I know the only things I don't have is dome override and dimmer.

Does anyone know how to upgrade to daytime running lights. It seems like the switch should be able to do it somehow.

[Otto]

the white is connected to the dome light in some way or another. What colors are left over on the orignal factory harness? looks like one or two are still left.

btw: you show that you used the brown twice on the new or old cluster?

[siveradoss22s]

I connected the headlight switch as mentioned in a post earlier. I also connected the white wire to the white wire and that made my dome and interior lights work. One problem though, the dome light isnt very bright and once I turn on my headlights my dome lamp dies.. Im assuming it has to be a ground problem..

Im going to check out the black wire fromt the older switch and connected to the other black , to see if that works..

Well I already have the dash in place.. Looks reAlly nice after I washed it this morning.. I have a blown up passenger airbag so Ill be fixin that and putting in the big hole. I was able to use the glove compartment unlike another memeber here.. I did have my computer box unscrewed so I was able to budge a little in to be able to close the little glove compartment door.

I will probably post pics up tommorow , my camera battery is dead and haven't had a chance to get a new one..

[siveradoss22s]

Anybody got specs on how to change the steering wheel? and how much money will it take??

[chevyz71man]

Does anybody have information on getting the newer cluster to work?? What wires need to be switched were and so fourth?? anything else have to be changed to make it work. I am going to start my swap on spring break. And I plan on getting all a/c wiring and headlight wiring done this and next week.

[v8sonoma]

The wiring on the back of the 95-98 headlight switch is......
red(+12v constant)
pink(+12V ignition)
black(ground)
purple(door switch input)
white(dome light output(switched with dome overide))
brown(+12V when parklights are on)
I know it isn't complete but i hope it helps...........

[Otto]

Here is the information from the chiltons book.

red- power.
white- goes to the left and right door switch. also turns on the curtousy light(i guess thats the overhead light when opening doors)
Green- connects power to the instrument cluster for lights.
Brown- parrking/tail lights.
Orange- fuse box, reads the 20A Park fuse.
Black- ground
yellow- Beam switch/headlight.

[Otto]

i hooked it up color for color. Everything works properly. i do have 1 wire left from the factory harness, brown, and four wires from the headlight switch( pink, purple, purple/white, grey). headlights work (both low and high), parking lights work, dome and interior lights work, instrument panel works along with dimming it, and th little buzzer comes on when its suppose to. My guess for the dome override switch is going to be the purple and purple and white lines. for the running lights my guess would be the pink line. i have no idea about the other two.

[siveradoss22s]

same here, everything works as for the headlight switch.. I was wondering how you can take off the lighter plug are off the dash.. I forgot to connect the wires to make my lighter plugs work before I put the dash in place and now i was thinkin it would be much easier to remove that part and connect it rather than pulling the whole dah back out since there is no space to get my hand in there.. ?

the only problem I ran into was my alarm goes on but very low everytime I connect hte battery back and stays on.. Im probably going to have to disconnect that **** for A WHILE. .

I was really hoping to get a diagram to swap the instrument cluster as well, but no luck yet..

that ashrtay assembly should unclip after you pull that bottom dash piece off. that shoudl allow enough room to connect those wires.

Im working on the cluster right now. the older gauges only had a certain amoutn of wires as the new cluster has a whole **** load more, maybe 10 more. i think im going to have to buy a manual with all the wiring in the truck, because this chiltons isnt too acurate. Right now i have the simple things like check lights, parking lights, stuff like that.

[siveradoss22s]

thanks man, let me know when you get that diagram.. i would realy appreciate it.. I dont really like the way it is going look with my original instrument cluster for now..

Im going to put my ac/heater controls where the slave cd player goes.. it fits pretty nice in there.. just need to make a little box around it so it wont be in there loose..

can yout ake a pic of how it is now? i dont see how you fit those in that little spot. i had a hard time putting mine in the a/c spot.

[siveradoss22s]

ill do that tonite once i get my digital camera.. it should fit really good, there is alot of space down there.. Im thinking about putting my airbag switches and gauge in the middle where the 98 AC controls belong.. ill post the pics as soon as i get a chance..

sounds cool. i planned on putting a double din dvd player in that area!

[chevyz71man]

So has anyone got the gauge cluster to fully work yet??? With the pre 95 wiring. Whats all involved if so. I just got a call that a 99 escalade went to the scrap yard a couple days ago. And it got wrecked in the rear end.....hmmmm escalade clip in junkyard along with 120mph cluster. maybe just maybe

[Otto]

that link posted above from rtv..... said he has done it. he is still working on the diagrams. i just ordered the 93 wiring diagram package and the 97 wiring diagram package so im going to be doing all the tracing down soon.

[Otto]

information on the gauge swap that i have so far. this is what i got so far this mourning. Ill be going through it again to make sure that they are all the same and that wiring is correct in the next few days. Dont blaim me if it doesnt work! haha.

93 truck / / Function / / 97 truck
A-brn / / Alternater / / 19- Brn

hey project 2005, nice rims on the truck.. they go with it real good..

hey, i understand your first post on the gauge swap.. wire color to another wire color, but on the post after that, you have some f,o,u or some letters.. what do they all mean? or maybe because im not lookint at the newer instrument panel yet because i dont have it at this point..


is it as simple as just finding out which wire connects to which or is there other things involved such as realys and **** like that.. ? I can get my gauge for about $70 from the yard, but i want to make sure i can get it working before i invest in that and just have it layin around..

i already have the dimmer light on the on the instrument panel to work, will the gauge swap affect it. will it still work.. are those wires involved with the lighting of the cluster already figured out in your diagram?

thanks...

[mr_goodwrench_0]

The letters or numbers he refers to are the pin numbers in the wirring harness. Like, if you look at the connectors, you will see that they are labeled with those letters or numbers.

Bill

[Otto]

yes, you wont be able to go by colors. you have to go from pin to pin. the 94- are A-Z, the 95+ are 1-32. Dont go by that diagram alone. I still have to make sure everything is the same inside the cluster before the diagram will be complete. Ill let you know for sure what it will be soon.

[chevyz71man]

Ok thats alot of very good info. Thanks alot by the way. Doy uo know if the speedo will work with the tbi computer being that my 94 has a Drac and the 96+ I dont think does. Or will something else need to be changed.

Also on the steering coloum, as we all know the 94 and earliers used a little piece of wire and a spring for the gear select....and the 95+ is electronic, Is all of that built in the steering coloum and I just need to wire that into it?? I will be using the new coloum.

So you are going to use the new column and steering wheel? How hard is it to change that? and how much money? I have my old steering wheel on, but it seems to interfere with the gauge bezel..

Also, which manual are you guys using? Do you recommend the one from auto zone.. I believe it is Haynes or somethin..?

I have no idea if any of this will work. This is just going from the two diagrams i have about how they wire together. I would think that the speedo would work since its just a signal coming in. I think all the DRAC unit does is convert it for tire size and gear size since this information isnt available for changing through the computer like it is on the ob2. after it leaves the drac, or computer, it only turns into a positive signal to the cluster.

As for that signal for the gear selector, I have no idea how to get that to work. They are pins 9-12 on the 95+ cluster. It shows that they go to a transmission range selector which is on the left side of transmission. let me search for that diagram real quick

[chevyz71man]

Well that selector thing I need anyways to use the new coloum. The pre 94 uses hard bars for the selector were the 95+ uses a cable, so I will be taking everything down to the part were it connects to the tranny. Hopefully the signal is the same otherwise I will have to run a 95 cluster. But I want the 6k tach... I am getting the whole dash, inner out door panels, coloum and tranny linkage, also the airbags to for 200 bucks. and another 50 for anyharness I steal, headlight switch and heater control and all the heater doors and harness.

[siveradoss22s]

My dash is already in place.. I was going to put my airbag switches and gauge in the location where the 98 ac/heater control goes but I decided not to. It looks good with the exception that the instrument cluster has gaps on the sides because it is smaller than the 98 cluster..

Also my dash shakes from the front where the windshield is.. I wasnt able to put in the 3 screws to tighten that are because it was too hard.. I think I might need longer screws since the original ones from my 93 dash didn't seem to make contact with anything and there waasnt enough space up there mess with a screwdriver..

I noticed some openings towards behind those openings where the screws go like if you can stick a screwdriver from the inside of the dash and have a good angle to screw them in..

[Otto]

the three on the top of the dash should just pop in. i used the original 1/2 inch long 7mm screw with about 5 extensions to get it in there...

[siveradoss22s]

Ohh ok, thanks, i guess ill try that today.. I was wondering, how is your dash coming along? I took some pics of mine, but I havent had time to post them up.. How do you post them as pics, not as links to the pic? Do you have any recent pics of yours? How is your gauge swap?

[Otto]

i just load my pics up photobucket.com, then use the link tag around the link to get it to show as a pic.

the dash has been in the paint shop for a week and a half. he said today at the latest, just waiting on teh phone call now! Im going to start the cluster in a couple weeks.

[chevyz71man]

Just thought I would let everyone know that I am going to be pulling my 98 dash out tommorrow and putting it in my 94. I will take some pictures and show all the wireing and what it took to get there. My spring break is from march 1st till the 12th. And it will go in then along with my GMC grille. Ill show what it takes to get the gear selector working and all. I have been doing alot of research and alot of digram following, So I am pretty sure it will go quick.

[siveradoss22s]

Here are the pics of my dash in place.. Im still wondering where to shove all the wires in this pic

I was going to put my dual needle gauge in this area along with the switches but gauge was a little too big so I put it down hanging on top of the lower panel..
http://i50.photobucket.com/albums/f348/silveradoss22s/HPIM0627.jpg
Here is my 93 instrument cluster for meanwhile.. need the diagrams still and the cluster.. The steering wheel Ill probably change to a billet wheel to save me some time and money on putting the 95+.. will also have a custom look..

[chevyz71man]

Did you get the doors all wired up and everything?? The progress seems to be going good. The cluster is pretty straight forward. I will have up my info tomorrow on the connections from my 94. Why not run the new column?? Did your headlight switch work from wire to wire??? I havent tried mine yet. looks good though

I hope you put the door actuator motors in for the new dash before you put it in.. Otherwise you will have alot of fun.

Thanks, I would really appreciate if you can post the cluster info tommorow.,, ill be buying my cluster tommorow..
Im looking into running the new column but I dont know exactly what parts Ill neeed and if it will be expensive and a pita to swap..

Yeah headlight switch worked pretty good.. wire to wire.. you will have a brown one left on the original wiring and probably about four colored wires left on the new headlight switch..

What do you mean by door actuator motors.. Is it those switches at the sides of the dash that have to be pressed in to turn the interior lights off.. if thats the case, yes I did? If not please explain..

[siveradoss22s]

As for the doors (window and lock swirches), I just extended the wires and ran them to the center console.. they look nice.. But, if I can get them to work before i start shaving of the control panels on the doors, that be great.. I can relocate my airbag controls there instead of them hanging there below the radio and AC on the lower panel..

[chevyz71man]

No i mean the motors to control the Vents in the a/c. They run differently and need to be swaped out. I have all the door wiring figured out I just need to get it all finished. I am working on figuring out what all involved in the column, righ now I am trying to trace the wires for the sector lights in the cluster.

PROJECT 2005 if you could use your diagrams and trace pin #8 on the cluster and see were it goes that would help alot. I think it goes to the purple white striped wire on the headlight switch.

[Otto]

hey, what size screw did you use for the top three holes? For some reason i cant get them back in like i had before hand. maybe my holes are just worn out now?

[Otto]

btw: heres how mins is coming along! http://i7.photobucket.com/albums/y272/onebadasstruck/880a4202.jpg

[chevyz71man]

Alright well I had to get some other things done today and only had a little over an hour to work on my truck. I only have the info on making the window and locks work on the pass door. First off the harness that plugs into the back of the control well go get 2 more of them so you have 4. Then the little white plastic retaining clips yank them out. Now there is two size plugs. You need to pull two of the small plugs from the donor harness and put them into the 2 spots that are missing on the good harness. You will notice on the switch theres 5 small plugs right in a row and only 3 wires. Once you got the new wires in your ready to splice, I cut the harness on the truck close to the door jam, but leave enough wire to work, just make sure to cut off everything sliced for that inner door. Then you will have 8 wires on the truck and 16 on the new inner door. First follow the speaker wires, and get them out of the way. Then follow the small 2 wire connecter that goes to lock switch and get those wires out of your way. Then finally follow the wire from the light on the door towards the back and get those wires out of the way. Now your left with 10 wires. I will get pics up tonight but for an explation of what splices were try to understand. pic will greatly help i promise. Hold the lock switch upside down infront of you so the tweater is farthest away from you. Now I am going to explain what pin on the switch goes to what color wire on the truck.
Top right corner - tan
bottom left corner - pink
top 2nd one in on the left - blue/white
Now you have windows
The lock wires are the 5 small pins on the bottom row I will list them from left to right. Remeber the left corner is not #1 the 1st small pin (the second pin in) is #1

1 - Grey
2 - orange
3 - Tan
4 - Blue
5 - Black/red
Now theres 2 wires left Simply splice them to there matching color on the truck tan to tan and grey to grey
Now you have locks.

Now for the light in the door you can use the door lock orange wire for positve and then use the white wire on the door jam switch for negative.
For the light in the switch just use a ground... and the parking light wire in the headlight switch. And speakers well do what you want.

Hope this wasnt to much reading....I will try to get to my drivers door tonight but if not wednesday for sure.

Dash looks awesome project 2005, I wish I had a black interior its going to look great.

[chevyz71man]

Were are you guys.... Figured you would have responded to working door locks by now...

[mr_goodwrench_0]

Maybe this should be a sticky.

Bill

[racer 2]

havent been able to work on door locks yet cause its been rainin and hasnt stopped yet

[racer 2]

yeah just got the passenger side panel hooked and the locks works great thanks for the info man

[siveradoss22s]

I kind of understand what you are saying but you kind of lost me in the part where you have to go get two more harnesses.. Hopefully you have some pics by now on step by step of what you did whith all those wires so I wont make any ****ups..

Anybody interested in SS replca rims in 22" for 5 lug chevys.. ?

[Otto]

pics of rims?

[BigBody90]

What does everybody do with the fuse panel when upgrading to the new dash? Should I make a custom plastic mount or is it easy to convert over to the new one?

[Otto]

i just pushed the old one in that location of hte dash, then tilted downwards. if i have to change a fuse i just have to lay on my back and look up...

[Otto]

[BigBody90]

Has anyone converted to the new one? It looks like it could be done with some connectors and a little time. I'm no electrical wiz though.

[chevyz71man]

I am going to convert to the new one. I am working on a whole write up of this entire swap. The only thing I need to figure out is the AC. I have been busy lately and havent had time to upload pics and explain everything. Spring break is only a few days away. Also I still need to figure out linkage for the new column

[siveradoss22s]

pics of rims?

I will be getting my rims on tommorow.. Then Ill show you some pics of them on an OBS and bagged that way you get an idea.. but if want a quic pic.. I believe some white crew cab has them on their sig or avatar whatever it is called.. I cant remember his screename of the top of my head..

[siveradoss22s]

I did the same, just shoved it up a little and hid iy under the dash.. maybe someday ill change to the new one..

[prettyman]

I have a 97 silverado with with all interrior options and a couple of years ago I took out the factory keyless entry for one of the acdelco alarms when it was installed the plug was cut out of the harness for the factory module, I no longer have the alarm and most of the power door locks and the interrior lights don't work without the module, and my tan dash is dammaged, so I am trying to locate either the whole harness or the pigtail for the module the one that will work is the plug with 16 pins and it is rectangular the module and the dash would be nice also I have been everywhere and I have had no luck finding these parts except at the dealership and they said I would have to buy a new harness, module, keyfob, and dash all for an arm and a leg!:hack:

[BigBody90]

I probably have the connector on one of my two harnesses, but I don't know about the module you need. Post pics of what it looks like and I should be able to hook you up.

How much is an arm and a leg?
