Products Featured in This Question
Question:
I have a 2020 JEEP WRANGLER UNLIMITED SPORT Willeys. It doesnt have a towing package and I would like to install a reputable wiring connector. I have a 2inch hitch already installed. I have looked at the 118786 T-One system and would like to know if that will work? Also need to know if there is a mount to fasten the plug to and how to test to see if everything is done correctly. thanks for your help

Hey Tim, the Tekonsha trailer wiring harness part # 118786 is the correct trailer wiring harness for your 2020 Jeep Wrangler Unlimited and would be your best option as it has the easiest install and most reliable converter box. For a 4-way mounting bracket the part # 18144 would be a really great and easy option.
For a quick and easy 4-way tester you could use the part # I26 as well. What will you be towing?

Just a small utility trailer for moving mower, etc. around. Don't think that they require a braking connector.
