This is the original wiring diagram printed by Ford for dealer mechanics. You can follow the wiring in your truck 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 will not find this diagram in your shop manual. The schematic measures 11" x 12.5" when folded up, and opens up to 11" by 24.5". Diagrams may be folded in half for shipping. The diagram pictured is an example of this type when unfolded, but is not the actual diagram for your vehicle. Buy now for the best electrical repair info--the factory wiring diagram.

Model-Years Application

To find out if you need a cab or a cowl wiring diagram, check the 3rd digit of the BODY code on the rating plate. The number 7 indicates that the vehicle is a Cowl, anything else would indicate that the vehicle is a Cab. On light and medium cowl and windshield vehicles, the Rating Plate is mounted on the right side of the cowl top panel under the hood. On all other vehicles, the Rating Plate is mounted on the rear face of the left front door. You do not need to check this if you have a B-Series, all B-Series are Cowls. This diagram covers: 1977 Ford B and F 600-800 Series models including B-500, B-600, B-700, B-750, B-7000, F-500, F-600, F-700, F-750 and F-880, F-6000 and F-7000.
