7 pin tow harness

[Spearmin]

I'm looking into towing a popup and I was told I need a 7 pin harness and brake controller. I think they make a Bluetooth brake controller that is plugg and play so that is covered. However, the harness is this something I can install myself. How much should I expect to pay if I get a shop to do it? How much is the harness itself. Has anyone done this themselves? I'm not looking for a week long project. Looking for something I can have up and running in a few hours.

Contact Jeep Parts. It should be a Mopar part.

I've done this twice, the cheap way and the right way. Get the Mopar harness, about $300, it will take you a few hours but work like a dream. I know some have had luck with the bluetooth controllers, but they are also easy to steal. I hard wired a Redarc and it's great.

I installed the Mopar OEM harness and 7pin, running the cable along the top of the passenger frame rail (not inside the cabin). Most of the work was dropping my bellypan for access, the actual install took a couple hours I recall. Quadratech has a video useful in particular for showing connection into the taillight.

I did the brake controller in a later session. While I liked the idea of the Curt bluetooth brake controller, I decided against it and installed hardwired Redarc controller. Why? I realized that if my trailer is fishtailing I didn't want to fuss with my phone, I wanted a button on the dash.

The install was also pretty easy, it's a Wrangler after all so the dash is designed like a lego, comes apart and goes back together easily (for installing the controller knob). Redarc has a good video also (would have to look up the link), and took a couple hours. The only time consuming thing was finding the brake controller wire under the passenger dash (it's there, forum posts were helpful). One more thing: since I have a MT there's no unoccupied firewall feedthru, so I routed the controller wire harness through the seam between windscreen and body, worked nicely. Forum posts about attempts to parallel a main feedthru on passenger side sound like disasters.

Good info. I would like to add that if yours didn't come with the tow harness pigtail under the dash, that important brake wire is inside black tape near the plug for the passenger door harness. I think there's a module there. I couldn't find it first time round, but more searching led me right to it.
