"1958 Chevrolet Truck Wiring Diagrams for Complete Chassis" This is a reprint of the wiring diagram printed by GM for dealer mechanics. You can follow all of the wiring in your vehicle from bumper-to-bumper. It will help you to understand connector configurations, and locate & identify circuits, relays, and grounds. Although the schematic is in black and white, the color of each wire is noted. You won't find this diagram in your shop manual (see my other items for the shop manual). The schematic measures 8.5" x 11" and has 8 pages, and is in brand new condition. The picture is an example of a wiring diagram, but is not the exact diagram for this vehicle. The manual covers all 1958 Chevrolet trucks, including pickup, panel, platform, suburban, light, medium and heavy duty truck models including ½-ton, ¾-ton, 1-ton, 1 ½-ton, 2-ton, 2 ½-ton, Cameo, Conventional, Low Cab Forward, Forward Control, Tandem Axle, & School Bus.
