Eckler's Classic GMC Trucks brings you a wiring diagram made to last a lifetime! Tired of those hard to read almost impossible to decipher black and white wiring diagrams copied out of 30 to 40 year old shop and repair manuals? We have the solution! All wire colors (including tracers) and component information is from the original GMC factory service manuals. This means the wire colors on the diagram are the same as what is in your GMC C, K, 10, 20, 30, Super Custom, Sierra and Sierra Grande. Ecklers Wiring diagram covers the complete basic truck including: interior and exterior lights, engine & engine compartment, firewall, under dash, instrumentation, etc. All text is crystal clear and easy to read, and all wiring colors are easy to distinguish. Wiring diagrams are laminated in heavy plastic for durability and ease of use. (No more grease smudged expensive shop manuals!). Field tested and mother approved with coffee, beer, soda, all kinds of grease, dirt and paint.
