If you're installing the American Autowire Classic Update Wiring Harness (510342) in your 1978–79 Ford Bronco, this Power Tailgate Harness Add-On Kit is a required component to complete the job properly. While the 510342 kit is designed for both Broncos and Ford trucks, the full-size Bronco's factory power tailgate window requires this additional harness to connect everything from the dash-mounted switch to the rear tailgate assembly.
Without this harness, your rear window won’t function—making this one of those small but critical pieces that ensures your electrical upgrade works like it should. Built with the same high-quality construction American Autowire is known for, this plug-in solution ensures clean operation and lasting performance. If you're building it right, don’t skip this step.
