Question:
I have a 2023 jeep grand cherokee 4xe with no factory tow package. I installed a tow hitch and the electrical wiring with the 4 pin plug. Is their a way to convert it to a 7 pin so I can get a brake controller for my trailer with brakes?

Hello Josh, there sure is! What you will need is the Universal Installation Kit # ETBC7. This kit contains everything you need to upgrade the 4-flat connection to a 7-way, including all of the necessary wires for a brake controller. For the brake controller, the Tekonsha P3 # 90195 is what I recommend. It is just a super reliable and user friendly controller.
Take a look at the install videos I linked for you below. Let me know if there is anything else I can do to help.

Hey Josh, did the Universal Installation Kit work out for converting your 4-pin to a 7-pin? I'm curious to know how it went because it could really help others looking to set up a brake controller for their trailer.
