Recommended 7-Way Wiring for 2017 Ford Explorer

Question

Question:

Greetings, I just recently installed a drawtite hitch. I purchased a HM40975 trailer connector. I need harness for a 7 way wiring harness. What would you recommend? I could return my current HM40975 and go with t one 118272.html and appropriate attaching hardware

For your 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - Vehicle End # HM40975 if you like the double function and look, you can keep it. You will need to get the T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # 118272 and that wiring can connect to the 7-way connection that comes with it or it can connect to your # HM40975.

This custom-fit T-One connector plugs into your Ford Explorer's factory tow package wiring harness, which is located beneath the vehicle, behind the rear tire on the passenger's side.
