BCM Wiring diagram

[thundermtx]

Looking for a wiring diagram for the BCM, specifically the door locks, exterior lights.............. am hooking up a remote start and need the info for the keyless entry side of the R.S.

Thanks for the web site. That helped a great plenty. Hoping the diagrams will be just as good.

E-mail sent, hope they help!

Thanks for all of those, that's going to be a great help. If I could get more: ignition switch, rear power vent windows, windshield wipers? Thanks again.

[83T/A98Blazer]

Sorry, haven't been here in a few days, still need those other diagrams?

[thundermtx]

Whenever it's good for you; yes, I am still collecting diagrams. The R.S. is a Christmas present for my wife and am waiting on getting it from E-Bay.

Can I ask why you want the the rear power vent and wipers? The info from the link I gave should be more than plenty to get your RS to work. What RS are you going with?

[thundermtx]

I'm going to close ALL windows when the doors are locked, and use the wipers to turn on the headlights when it's raining.

You do know that you'll need a window module to make them work with the remotes. On the wipers, I'd use a timer relay. If you don't, even if you hit your wipers for one second, the lights will come on and go off for one second. Instead, I used a module for the lights from Directed Electronics. Now, my lights have daytime running, turn on each time I use the wipers, and also come on by themselves when it gets dark enough out.

What year car? Make sure to be very carefull when probing around on a Venture van. These cars are riddled with enough electrical gremblins as they are now.

Here's for a 1998 van.

hi im new here and i think i have ground electric problem with my brake ligths, i change the circuit boards, the plugs that go in to the boards. still the same problem. i want to try to look if there is a short circuit in the wiring. but i dont know where the wires lead to any of you know if they go under the carpet. dont see them under the carriage.

Did you change the wiring harness and plug that plugs into those rear taillight assembly mating, supposedly weatherproof plugs? If you did not, that's probably where your problem is. Unplug itand look for a slight burn in the middle wire/plug area. If so, you need to mark the location of each wire to the mating taillight prongs and then cut that bad plug/connector off, attach wire leads to each wire and plug them into the mating prong on the taillight plug. Once they all work, apply silicone weatherproof caulk to the whole assembly and let dry overnight. Works like a charm on 97' and saved me the expense of a new wire harness. Any ?s, email me at [email protected].
