I've searched through alldata, autozone and several other places. I cannot seem to find this for the 93, anyone have it by chance? I'm sure it was right in front of me at some point but Ive been reading diagrams and sorting through wires for 5 days now and they all start to blend together. Before I start tracing wires back I figured I'd ask.

Thanks,

 

are you talking about the wires that go the computer or transmission or where exactly im kinda confused? i have some pdf files when i was issues with my 93.
if youre talking about the trans shoot me a pm with your email address ill just send you the file, its like 80 pages, i just skimmed through it has a bunch of electrical connector views

also i just looked again, does look like it has some of the computer connection wires.

 

i Do have a gm service manual for an 92 Id be glad to take some shots of pages you need

just let me know what exactly you need

there should be no difference between the 92 and 93 i think ... =P

 

Yeah, I have a 1992 Bravada service manual. I found a couple of differences, but not anything noteworthy.

 

Thanks everyone. What I'm looking for is the actual wiring connection at the firewall, It is labeled as C100 in my alldata. The back of the fuse box is on the inside of the firewall and the other two halves are on the outside, one to the front clip and the other to the engine.

I have the ECU diagram as well as the under dash, body and trans but cannot find a diagram like the one I have for my jeep.

 

I dont know if these help but ill keep looking for you
those are the closest ones the gm service manual has of the firewall and the cab

Thanks for the help everyone. RetroBlazer, somehow I didn't get the post notification and just popped in to check it. Appreciate the info just north of you in Gtown.

 

Well how do neighbor. I have most of a 1993 dash wiring harness if you need it (I used the hatch release wiring and speaker wiring).

 

I hope that the one I have still functions after I hacked out all that I don't need. I kept having lethal weapon flashbacks, I'm thinking we should cut the blue wire, that's not what I'm thinking. I have a pile that includes hatch release and everything else not required to run.
