I am working on a 1997 k3500 auto 4x4. It had a bad 5.7, so I installed a 7.4l. I used the wiring harness from a 1996 k3500 7.4l 4x4 auto.
The engine and tranny work well, but a few things aren't working, and it seems the c100 firewall connector are not the same from this 1996 wiring donor truck to the 1997 that I am working on.
Tachometer not working
Alternator not working
4x4 not working (haven't verified that the c100 connection is to blame)
I can and have found several c100 diagrams but none specifically for a 1996. I have only once heard that they too have seen different pins on a 1996. Most others say they are all the same for all years, but that doesn't seem to be the case.
Before I re-pin my connector to match it to the 1997 truck, I would love to have a 1996 C100 schematic. Any help appreciated.
