Written for dealership mechanics, this wiring diagram shows you how to follow the wiring from bumper-to-bumper. It will help you understand connector configurations, and locate and identify circuits, relays, and grounds. You will not find these wiring diagrams in the factory shop manual. Wiring diagrams are black and white, but they frequently have color codes printed on each line of the diagram that represents a wire.

Why buy a factory manual?
Fix it right the first time with the factory repair manual and save money by doing the job yourself. Factory experts prepare these manuals for their dealership service departments, so they're the most complete and specific source of repair techniques. Repair manuals are also called shop manuals, maintenance manuals, service manuals, or technical information manuals.

This manual covers 1972 GMCForward Control or Stepvan, including half ton, three-quarter ton, one ton, P 1500, P 2500, P 3500. These are steel and aluminum bodied parcel delivery trucks (similar to a UPS truck or bread truck), or the chassis for one of those trucks with another sort of body on it. The GMC is sometimes called Value Van. To verify that this is the correct diagram for your truck, you can check your VIN code. The 2nd digit should be a P for the forward control model, the 4th digit should be a 1, 2, or 3 to indicate the 10, 20, or 30 series, and the 6th digit should be a 2 for the 1972 model year. See my other items for the motorhome diagrams.
