This is the original wiring diagram printed by GM for dealer mechanics. You can follow the wiring in your truck from bumper-to-bumper. It will help you to understand connector configurations, and locate & identify circuits, relays, and grounds. Although the schematic is in black and white, the color of each wire is noted. You will not find this diagram in your shop manual. The schematic measures 8.5" x 11" when folded up, and opens up to 11" by 38". The diagram pictured is an example of this type when folded, but is not the actual diagram for your vehicle. Buy now for the best electrical repair info - the factory wiring diagram.

Covers medium duty Chevrolet and GMC right hand drive conventional truck models C5, C50, C5000, C6, C60, & C6000. To verify that this is the correct diagram for your truck, you can check your VIN code. The 2nd digit should be a C for the conventional cab, the third digit should be an S for the in-line 6 gas engine, the 4th digit should be a 5 or 6 to indicate the series, and the 6th digit should be an 6 for the 1976 model year.
