Early Bronco electrical systems are nowhere near as complex as those of modern cars, but even wiring as simple as these can be a headache to troubleshoot and repair. Shade tree mechanics and veterans alike can all use the help of a wiring diagram.

Luckily Bronco wiring diagrams are easily accessible either on the web or for sale inexpensively on places like eBay. You can get them in paper form, bound books or even scanned to CD so you can view and print as needed. Look for those that are color coded, which really makes tracing down those electrons easier.

Ford changed the Bronco slightly from year to year from 1966-1977, but it’s usually not critical to find your exact year. If you’re having trouble locating your year try getting one a year or two later. If anything those diagrams will have more information instead of less.
