4-Flat Wiring for a 2021 Jeep Wrangler Sport and Where to Mount the Converter to Keep Elements Away
Updated 12/30/2024 | Published 12/28/2024 >
Question:
Good morning. I own a 2021 Jeep Wrangler Sport. I am interested in installing the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector Part Number: 118786 kit on my vehicle. I have one question if I may. Is it possible to secure the converter boxfoot inside of the driver’s side rear light housing? I am concerned about installing it on the outside of the vehicle and the exposure to road grime and external elements. Thank you for your assistance. I will wait to hear your thoughts / suggestions before ordering.

Hello Carlos,
Yes, you can most definitely secure the converter in the inside of the driver side rear light housing. The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786 will be a great fit for your 2021 Jeep Wrangler. I went through the reviews and I see that one of our customers did the same thing, I attached the picture of where he installed the converter. I would also recommend grabbing a Mounting Bracket 4-Pole Flat # 18144 for a clean looking install.
Happy New Year! May 2025 be your best year yet! From, your friends here at etrailer!

Kate F one follow up if I may... Thank you so much for the timely response. My ultimate goal is to install a 7 pin round plug as well and know that etrailer sells a flat four adapter to 7 pin to facilitate. My question is will I have to run a seperate hot wire from the battery to the 7 pin round receptical? Or will the hotwire from the battery to the 4 pin flat converter be enough to power the 7 pin round connector. Thanks, I hope that makes sense. Happy New Year.
