Underdash Wiring

Though restoring a First Generation or Fox Body Mustang can be an enjoyable practice for muscle car enthusiasts, the process rarely comes without one or two hiccups along the way. In addition to locating and purchasing the correct OE reproductions, tracing faulty wiring is one of the biggest hassles of restoring a classic Ford Mustang from the ground-up. While all Mustang wiring is important, tracing, and eventually diagnosing your Mustang underdash wiring can be a tremendous challenge. Because of its physical location under the dash and that it is responsible for powering multiple different areas of your Ford Mustang, it is important to always be mindful of your Mustang underdash wiring harness.

Entering your firewall behind the Mustang instrument cluster, your Mustang underdash wiring harness provides power to numerous other clusters within your interior and engine compartment, including your Mustang instrument panel, the console feed harness, the Mustang door light, the windshield wiper motor, and much more. All of the wires that connect to these various harnesses and devices are well-organized and color-coded within your Mustang under dash wiring harness. While the harness is home to most of the Ford Mustang underdash wiring, wires that power your Mustang radio are also important circuits that reside underneath the Mustang dash.
