Welcome to DieselPlaceI am in need of the wiring diagram for a 2005 GMC C5500 diesel.
It has stopped working alltogether. My mechanic said it is an electrical issue - computers are not comunicating. Any help is appreciated.
GMUPFITTER.COM, go to the body builder page go to your year.model and look for the specific electrical manualHi, I'm looking for the wiring for the steering wheel controls and warning chime to the radio. I installed an after market radio and cut the wiring to splice it in before I found out there was an adapter kit ( thanks Atoto and Amazon). It's for a 2008 2500HD.
Thanks in advance!
