Description  more details

Written for GM 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. Buy now for the best electrical information available.
