Review on 🚗 Efficient Trailer Brake Controller Module for 2015-2020 Ford F150 JL3Z2C006AA - AUTOKAY brand by Quinton Dawon

Broken Switch. I installed the switch and set up a 2018 Ford Expedition with ForScan. The boost worked well. Gain down was VERY finicky and didn't work consistently. The button had to be pressed at an odd angle for it to work. At the end of our first trip with a trailer, the switch failed completely, constantly braking the trailer at full power. Error towing trailer with trailer power cable/brake connected to our vehicle. Had to complete the trip with the trailer cable disconnected (and no brake lights) to tow the trailer home. Removed this switch and put in an OEM factory part and it works great now. Buy factory parts and don't rely on cheaper imitations for critical parts. If you want to risk failure and save a few bucks, give it a try.
