Add notes:

All parts from 88-98 are interchangable with one and other. This means that all parts in the 88-94 style interior WILL fit into the 95-98 interior and visa-versa.

Tech notes:

98 dash install: All three bolts on top and the top on bottom line up perfect. The a-pillars and kick panels also snap right into place.

sweet deal! now this one needs to be a sticky, since these are proven diagrams. glad to help out!

[MStefak]

Figured it was a good idea. I know the door panels work because I've done it and I figured you, Project 2005, seems to know what your doing and it should be correct.

Like I said as more info and ANYTHING as far as the difference in interiors arises I will post. Also stock seat mount brackets and the different holes you have to drill will be posted soon as well, dimensions and all.

[siveradoss22s]

Ok Im looking at the the door panel swap with power. I kind of understand it now. I had posted earlier that I was confused, but it is starting to make sense. But, I still dont see if both side are the same.. MAybe when I have the harnesses in front of me I will be able to tell. Anybody have any wiring drawing or pics to make my life easier..would really appreciate it..

Stuck!

[MStefak]

Pimp my first sticky! haha

I'll try and get this info so you dont have to always download the new file.

[LS6TT]

Best post ever right there!!! Good job!

[MStefak]

I cant take full credit for this information as of now this would not have been possible with the help of Project 2005 and SilveradoSS22s.

[MStefak]

Soon I will be offering ' Quick Wiring Harness Adapters '.

What this will be are two pigtails one 88-94 and one 95-98 with 3-4 inches of wire inbetween. The harness will have the appropriate wires going to the appropriate pigtail number/letter. They will be available for Door panel swaps WITH power , Cluster swaps, and A/C heater controls which will include proper relays in place.

This will allow for a quick safe way to adapt one style to the other!

[siveradoss22s]

Thats a great idea.. MONEY MAKING IDEA.. some people who aren't to familiar with electric stuff, would rather just get a plug nad play kit to convert..

Good luck man..

[MStefak]

Thats what I was thinking. They should be farly easy to make.

[MStefak]

Before the question gets asked I'll answer it.

The letters are like PIN Numbers. They specify what wire it is. If you look at the pigtails you will see these letters.

[Otto]

the newer panels dont work like ours do, but you can make them so that they do, or so i hope.

[Otto]

ok, someone try that out and let me know how it works.

THIS IS KIDNA HARD TO WRITE DOWN, ILL BE WORKING ON IT A LIL MORE IN A WAY TO UNDERSTAND IT. AFTER THAT ILL WRITE DOWN THE LOCKS/UNLOCKS

this makes more sense to me, since I couldnt locate the matching colors.. Ill try this tomorrow.
Also, what is meant by convenience center?
Ill try this tomorrow afternoon..

[Otto]

i have no clue in hell. jsut connect them i guess, since they come up on both iagrams

[chevyz71man]

I have pictures of the door locks right now, I am uploading them. They have pics of wht wires needed to be added to the 95+ switches and how to make it work. There is no way to make it work without adding wires unless you run 4 relays for the lock motors. Trust me the 94s use whats called reverse polarity locks and 95 ups dont.

[Otto]

yea, i was noticing that on the swap. i was just trying to bi pass how they hooked up... im interested to see the pics
