1990 GMC C/K Sierra Pickup Wiring Diagram Manual 1500 2500 3500

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. Buy now to own the best electrical manual for your truck.

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 all 1990 C and K Sierra Pickup Truck models, including half ton, three-quarter ton, one ton, 1500, 2500, 3500, extended cab, dually, two wheel drive and four wheel drive. Includes both gas and diesel engines. This manual covers the "new style" C/K trucks for 1990, they do NOT have wing windows. If your truck has wing windows, see the R/V series truck manual. This contents of this book are the same as the 1990 Chevy CK wiring diagram, only the cover is different, so this book can be used for those trucks also.
