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.

This book covers 1976 GMC and Chevy 7500 and 8000 Conventional models also known as HE-75, HE-80, JE-75, and JE-80 equipped with a gasoline engine. See my other items for diesel diagrams. To verify that this is the correct diagram for your truck, you can check your VIN code. The 2nd digit should be an H or a J for the heavy duty steel conventional cab, the 3rd digit should be an E for V8 gas engine, and the 6th digit should be an 6 for the 1976 model year.
