Aftermarket power door locks

[ynot]

A while ago I had a viper 790xv alarm installed on my truck along with door lock actuators . I got a catalog from LMC Truck in the mail today and started looking threw it . I found the factory door lock switches and started thinking . Can I hook up the factory switches to aftermarket actuators/alarm so that I can lock/unlock the doors without the alarm remote? If anyone has info on how to wire this let me know .

theres a wiring diagram in my Haynes book that can help i dont have scanner so i cant post it ...buy one !

Yes it can be done, you'll need to tie into the relays for the actuators. However without knowing which wires on the switch serve what functions I couldn't really tell you how to wire it at this point. I'll see if I can find a wiring diagram for the switches on-line somewhere, but it might take some research. The good news is the hard part is done for you already (installing the actuators and wiring the relays up).

From the looks of it the switch has 3 terminals which I'm guessing are lock,unlock,and either constant power or ground. I can't seem to find ant pics of the backs of the switches though .

If you've got an ohm meter you can figure out how they work pretty easily, 2 of those wires should have no connection at all when the switch is thrown in either direction(those will be the lock & unlock wires) the remaining wire should be the constant wire connect one lead of the ohm meter to it and the other lead to either of the other wires and trigger the switch in both directions. If the ohm meter goes to zero in the unlock postion that wire is unlock making the remaining wire lock and vice versa. Now the only thing left to do is find the relays and figure out if they are positive or negative triggered. If I recall correctly viper alarms trigger relays with a negative pulse by default. You'll have one relay for lock and one for unlock. If they're negative trigger connect the constant lead to ground and the other to to the relays where the alarm connects to them. If they're positive triggered connect the constant line to +12v (make sure you fuse the line though). If you need more info I can walk you through testing the pulse to see if it's positive or negative.

Thanks for the info . I let know if I need help when the time comes .
