To install a 7-way and brake controller in your 2019 Jeep Wrangler Unlimited first requires you to install a 4-way connector part # 118786 which provides all of the trailer lighting functions and then convert to a 7-way with the part # ETBC7 which the 4-way plugs into and comes with everything needed to wire up a brake controller. I attached an install video for this kit on a similar 2012 Jeep Wrangler Unlimited as yours for you to check out as well.

For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.

I’m looking to upgrade my 2017 Jeep Wrangler Unlimited from a 4-pin trailer connection to a 7-pin with brake controller to pull an R-pod travel trailer. What will I need? Thank you.

My personal recommendation here is a combination of the Wiring Kit # ETBC7L and the Curt Echo Brake Controller # C51180. The Wiring Kit includes everything you need to convert your 4-Way to a 7-Way (plus wiring to activate the 12V circuit). The Curt Echo then simply plugs into the 7-Way and pairs to your smart phone via Bluetooth, eliminating the need to add anything extra inside the vehicle (like with just about any other controller).

Hello Mike, Happy to get you the right wiring. I looked up the hitch number you mentioned the E99856 and I am not seeing that we have that in our system. In fact I do not see an etrailer branded hitch for your 2025 Jeep Wrangler Sport S Unlimited. So…

I am not really sure what you are trying to do but you can install a trailer hitch on the rear of a trailer. There are two different kinds of trailer hitches for trailers, frame mount and bumper mount. The frame mount hitches are much stronger but…

Hi Ken, Starting with the wiring harness, I can verify for you the correct fit for the 2018 Jeep Wrangler Unlimited without a tow package is indeed the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector #118786. Then for the hitches, the…

Hey Rick, that's really a pretty odd problem to have from your Curt trailer wiring harness part #56407. Do the taillights of your Jeep also still work when the vehicle is on? Where do you have the red power wire of the harness ran to on your…

Answer 6

As long as there isn't anything connected to the trailer wiring's 4-way when you are flat towing (there shouldn't be) it wouldn't matter if you install the diodes of a tow bar wiring kit like #RM-15267 before the trailer wiring. It…

Answer 7

You'll have zero issues using both a trailer wiring harness like the Tekonsha #118786 and a plug-and-play flat tow harness like the #BLU79FR on your 2021 Jeep Wrangler. They'll plug into each other just fine, and since only one of the…

If you are looking for a quick and easy plug and play wiring to get your 2021 Jeep Wrangler JL set up to be flat towed behind an RV, then the Curt #C96JR will not require a wire to the battery. This will plug in behind the tail lights and then follow…

Answer 9

You can go from tow bar wiring to a 4-flat trailer connector on your 2022 Jeep Wrangler 4xe, as the two will simply plug in-line with one another, so no splicing is needed. So with your tow bar wiring all you need is the T-One Vehicle Wiring Harness…

Answer 10

Hey Bryce, the Tekonsha trailer wiring kit part #118786 that you mentioned would not interfere with the tow bar diode wiring kit you have installed currently.

Answer 11

The connectors of the Tekonsha kit part #118786 that fits your 2020 Jeep Wrangler Unlimited are pass through. If they were not the vehicle taillights would not function after the install. What this kit is designed to do is detect the signals that are…

Answer 12

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…
