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 Astro 95 and Chevrolet Titan 90 models with the VT903 Cummins diesel engine, also known as DB-9003 or DB-9502. See my other items for other engines. To verify that this is the correct diagram for your truck, you can check your VIN code. The second digit should be a D for the aluminum tilt tandem cab, the third digit should be a B for the VT903. The 6th digit should be a 6 to indicate the 1976 model year.
