Question:
I have a 2021 Ford F150 Powerboost with an integrated trailer brake system that continually s out Trailer wiring faultinch leaving me without trailer brakes until it kicks in again. The trailer has been hooked to other trucks and the brakes work fine. What adapter will I need for the Tekonsha 90195 and do you have any installation tips? Thanks!

Hey Gary! To install the Prodigy P3 Brake Controller item # 90195 in your 2021 Ford F-150, you'll need the Plug-In Wiring Adapter for Electric Brake Controllers item # 22292. The connector you're looking for is going to be to the left of your emergency brake.
We actually installed the P3 item # 90195 in a 2021 F-150 and made a video. I have linked it below. This will walk you through the entire installation process.
