1991 Cavalier V6 Wiring Diagram

I'm in need of wiring diagrams from the GM service manual only for a 1991 Cavalier with a 3.1 V6. Mainly of the pinouts from the ECM but the driveability and emisions section fo the manual will have about 5-6 pages with the complete set concerning the engine bay. I want to compare them to my 1990 setup as a few of you already probably guessed that I want to run the '91 eprom for obvious reasons

I have a service manual for a 91 sunbird. It's at my parents house, so I can take a look tomorrow for ya.

That would be cool, the harness was originally out of a '91 Bird 3.1 from back in the day, I made it into a 2.8 auto and then to a 3.1 auto and then to a 5spd, and now back to its almost original form

I'm sleepy and it's after 4 in the morning but I think that this is what you want. Hope these help. Oh and thanks for the positive note in the buy/sell feedback thread.

Oh and excuse the notes, these are fom when I did my trans swap.

These are general so I'm not sure if they are what you are looking for, and if you need any others let me know.

Perfect mang! Thanks a lot, Now I can compare it to the ones in my '90. I love the GM shop manuals, you can wire a car from scratch

Hey Feavs, is that manual have everything in just one book, or is all the electrial in a book seperate from the mechanical info? The reason I ask is that I have the 1988 shop manuals, and all the mechanical and body info is in a really thick (like 1000 page) manual, while the electrical diagrams are in a smaller, couple hundred page supplementary book. Then, when I was looking for a 92 manual, the only ones I could find described one book, so did they put all the electrical info into the first book, or is the manual I was looking at missing a book?

both my 91 and my 92 book have both electrical and mechanical/body in one book. I don't know how many pages, but well over 1000.

Yo, you wouldn't happen to have the wiring diagram for all the extra accesories inside the car, such as the headlights,windshield wipers, or relays, that run everything?

Not the GM ones but I have AllData all fired up and awaiting whatever you may need!
Just tell me what exactly and I will send you a diagram!

Cheers

ok, well my windshield wipers don't work at all, checked the wiring, and i don't see any problems, the fuse is alright, yet the wiring is getting no power at all. and i can't seem to figure it out, I basicly need to know where the switch gets it's power source from, and which prong is the power, the ground, and the high and low settings, so basicly i need a diagram of everything from the power source, to where the wires go to the witch, to where they connect to the wiper motors, if that makes any sence.

Oh BTW is the solid white wire, the one I tie into for the tachometer signel for my after market tach?
