What is Needed to Install Brake Controller in 2015 Jeep Cherokee Trailhawk

Question:

Thanks Kyle, I do have a tow package, but unfortunately it was not included with the sale of the Jeep, I had the tow hitch and wiring done at the dealer after the sale. It looks like all I need is the break control unit. Do you have instructions on how the wiring would be installed on that unit as it’s not plug and play? Thanks again

In order to have a plug and play brake controller, your 2015 Jeep Cherokee Trailhawk would have to have the factory tow package and factory trailer connector. If you have those things, you would have have a plug-in option, with the connector being up above the emergency brake pedal under the dash.

If you do have that you would be able to use:

- Custom Wiring Adapter for Trailer Brake Controllers # 3014-P
- Tekonsha Prodigy P3 Trailer Brake Controller # 90195

The Prodigy P3 is the most reliable brake controller on the market and is very simple to use with its clear display while also giving you the smoothest braking so I strongly recommend it.

If it turns out you do not have the factory tow package or a factory trailer connector then you can still use the Prodigy P3, but you will need a couple of other parts:

- T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118605
- Universal Installation Kit for Trailer Brake Controller # ETBC7
- Tekonsha Prodigy P3 Trailer Brake Controller # 90195

This will give you the connectors needed to install the Prodigy P3 brake controller in your Jeep. I have added a link to video reviews for you to check out, an install of the 4-way on a 2015 Cherokee, and a couple help articles on brake controllers to take a look at.

Question:

Good evening, I’m wondering if it is possible that not all 2015 Jeep Cherokee trailhawks don’t have a plug and play for a brake control unit? I have looked all over the web and YouTube as well as your website to see where it would be and I am not finding one. If not, what would be used to install a break control for a trailer with brakes? I have included pictures from under my steering wheel Thanks in advance

So it sounds like you had a 7-way installed on your 2015 Jeep Cherokee, but if it didn't come with it, then it isn't the "factory" OEM tow package. What that means is you will need to hardwire your brake controller like the Prodigy P3 Trailer Brake Controller # 90195.

If you do have the 7-way, wires to connect a brake controller should already have been run, and you will hardwire the controller just like in the "Brake Controller Installation" help article I added, starting at the section halfway down that refers to wiring the brake controller. You will need to locate these wires though, and use Butt Connectors # 05731-5 to connect them. At worst, you would need to trace the wires back from the 7-way to see where were run.
