Parts Needed to go From 4-Way to 7-Way for Brake Controller on 2018 Jeep JL Wrangler Rubicon

Question:

I have an existing 4 pin hookup on the back of my 2018 jeep Wrangler Rubicon. I would like to covert to a 7 pin for electric trailer brakes and install a proportional brake controller. What parts do I need. Would also like to keep a 4 pin hookup.

We can absolutely get you the right parts to add a 7-way and brake controller with your 2018 Jeep Wrangler Rubicon. Since your Jeep already has a 4-way like the T-One Vehicle Wiring Harness # 118786, there is only one other part you will need:

- Universal Installation Kit for Trailer Brake Controller # ETBC7

This will give you a 7-way connector, circuit breakers and the rest of the hardware needed to install a brake controller. The face of the 7-way does have a plug-in for a 4-way as well, so you will be able to connect trailers that have either a 4-way or 7-way.

After that you will need a brake controller, and for that I highly recommend the option from Redarc, and you'll also need the wiring adapter:

- Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR

- Wiring Adapter for Trailer Brake Controllers - Jeep # 3073-P

I really like the Tow-Pro Elite because of its control knob which keeps a cumbersome unit out of your cab, and and because it gives you more control over your trailer braking power than any other brake controller.

The control knob of the Tow-Pro Elite can be installed anywhere you like in your Jeep, so you'll have more space and won't be bumping your knee against a unit that has to mount under the dash, which is a bane to the majority of brake controller users.

The other thing the Tow-Pro Elite does better than any other controller is give you control. It has two braking modes, the standard proportional control, which powers your trailer brakes with the same intensity as your vehicle brakes, or user-controlled mode, which allows you to apply the brakes with a pre-set amount of power your choosing. This can be really helpful in a number of situations, like going off-road or areas with longer descents because you can set your trailer braking to a higher intensity to keep the trailer from pushing your Jeep.

Question:

Can I use the Curt Echo Wireless Brake Controller instead? Don't want the hassle of wiring the brake controller in the interior.

Expert Reply:

Yes, if you'd like you can absolutely use the Curt Echo Wireless Trailer Brake Controller # C51180.

This is a very simple brake controller to use and will absolutely work along with the Universal Installation Kit for Trailer Brake Controller # ETBC7.
