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 the 60002 and 60062 series bus chassis. To verify that this is the correct diagram for your truck, you can check your VIN code. The 2nd digit should be an S for the school bus chassis. The 6th digit should be a 3 to indicate the 1973 model year. Covers both gas and diesel. Also covers the CE/CS 5002-6002 models with RPO code K76, K79 or K97 (for dual brake system).
