Question:
I changed vehicles and I would like to put my Tekonsha brake controller in my new vehicle. Do you have any info on installation in a 2021 Ford Explorer without factory wiring?

Hey Scott! Congrats on the new vehicle! To install a Tekonsha brake controller you'll need the Replacement Brake Control Plug-In Harness for Tekonsha item # 20127. The 2021 Ford Explorer's did not come with a plug in port if you do not have any factory trailer wiring.
I have linked an installation video below to show you exactly how to get it set up.
Here are the rest of the wiring harnesses you'll need to set your Explorer up to tow a trailer with brakes:
4-Way Connector - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # C56093
and
7-Way Connector - Universal Installation Kit for Trailer Brake Controller - item # ETBC7
If you have any additional questions go ahead and throw them into the comment box below.
