[Small White Car]

Work truck is a 2003 Chevy Silverado 3500HD with the 6.7l turbo diesel, whatever, my issue is with the other end.

It has a custom bed on it designed to lift and carry three yard trash bins, like forklift on rails sorta, that too is irrelevant though because all that stuff works fine.

What is clusterfuck however is the lighting on the back of the truck and the 7 pin connector. Seems they cut the harness end off and scabbed it together like some high school kids Civic. I've got 15 wires coning out of the loom at the back of the truck and was wondering...

tl;dr Anyone know where I can look at a wiring diagram or schematic for free so I don't have to run around the truck like a monkey with a test light more than once? Maybe even tonight?

Paul might have a better answer, but if not, talk to Zack at speed scene wiring. He has, or has access to GM wiring diagrams.

Install guys at Best Buy can pull up wiring diagrams, throw them a tip theyd prob print it out for you. Not sure if they go that far back though, usually its just the dash wiring.

Otherwise buy a multimeter for $10 at home depot and work the controls as you test each wire.
