"1990 R/V, P Models Electrical Diagnosis and Wiring Diagrams" Written for Chevrolet dealership mechanics, this factory-published original 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. It is a set of loose-leaf sheets. Because the sheets are oversize, they may be folded in half for shipment. This covers 1990 Chevy P-series trucks, including P20, P2500, P3, P30, & P3500 that are three-quarter ton and one ton models. It covers Step Vans, both steel and aluminum-bodied Value Vans, and forward control chassis that were used as the basis for parcel delivery vehicles and other trucks. Includes class A forward control motorhomes chassis. This manual covers the part of the motorhome manufactured by Chevy and will not cover motorhome bodies.
