Hey Ron! Do you have the tow package on your 2025 Ford Bronco? If it didn't come with the towing package those circuits probably aren't activated. The other functions on the # C36GJ won't work until you take it to your local dealer for activation.

Hey Robin, When I researched the product and talked and emailed with your representatives nothing was ever mentioned! Probably spending half a day at a dealership is not in my top 10 options at this point.

@Ron I understand, I would be less than thrilled myself. We have it listed in our tech tips but if you don't get to the part through the fitguide it is easy to overlook. The reality of it is you would have to do that for any plug and play. And it still beats installation time and costs that would come with a universal part. Just to be sure, you can test for power on the factory wiring running to the connector to rule it out. I looked earlier and I'm pretty positive they have activate it via the computer on the Bronco, but it would be worth checking to see if installing some fuses/relays on your own would take care of it.

@Ron it isn't a link I can send, more like a note. If you have 2025 Ford Bronco in the fitguide and choose "Ford Bronco Trailer Wiring" it will be on that page. Scroll down until you see the # C36GJ and it is listed right there. Tech Tip: It may be necessary to see a local Ford dealer to activate the tow package wiring circuit.
