I 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.

Hi, 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!
