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 GMC Astro 95 and Chevrolet Titan 90, also known as D9, equipped with the GM 12V-71 diesel engine. To verify that this is the correct diagram for your truck, you can check your VIN code. The 2nd digit should be a D for heavy duty aluminum tilt cab, the thrid digit sould be a P to indicate the 12V71 diesel, and the 6th digit should be a 3 for the 1973 model year.
