I can help further with '95 C3500 wiring diagrams, if you can be alot more specific as to what your looking for.. There are literally hundreds of wiring schematics..
Take "Section 8A-27- Engine Controls" for example, theres aprox 15 different wiring schematics in that section alone. Then you'll likely need several other partial or complete sections to connect all the dots....

Any chance I could get these? I would like to wire up a relay to turn on the rear a/c blower when the a/c is switched on to help keep from dumping liquid Freon back into the compressor or whatever it is that causes the compressor to fail prematurely. It seems like it would be a lot easier and cheaper than the TSB I have seen floating around.

If you have a general link to all of them that would be much appreciated for future use.

Thanks.

I need some help.
I picked up a 95 gmc 3500 extra cab 4x4 which had a nv4500 and a 6.5 in it. When I got the truck the owner pulled the 6.5 and nv4500 and took the engine harness too.

The help I need is in identifying the wires that are at the main plug on the drivers side firewall. I picked up a plug from a salvage yard with about 18" of wires. I am putting in a 5.9L 6bt Cummins backed by another nv4500. I want to hook up as many factory wires as I can because I want to utilize the factory gauges along with the A/C and heat. If you can help I'd appreciate. Or need more info I'll do my best.

Thanks in advance.

You really should get the entire underhood harness off any 95-99 truck or burb any engine to start with.
You will have an extremely difficult time getting things to work and spend a lot more time and money tying to manage it with just the C100 connector.
There will be minor differences from one to the next but all you have to do is move the terminals to the correct hole for your truck.

The pass. side is a pass-thru, not a connector. In the service manual wiring diagrams it is P101.
I have not made a list for that because I have never needed to.
