GMC 1991 Wiring Diagrams?

[BlueManLou]

Hey Guys, this wiring manual is good for the GMC too, right?

• 1991 ST-375-91-EDD GM CK Light Truck Wiring Manual ** NEW 3/2016

Sorry, I am not too familiar with service manuals, I am a computer guy... I did flightline avionics work on the F16 while I was in the USAF, so I can read schematics and shoot wires...

The only real differences between the Chevy and GMC trucks from this era were cosmetic, so yes the factory service manuals will apply to both. As long as you've got the correct year manual you should be good to go.
