Mopar 7 Way Round Trailer Connector Reviews

Works perfect for my 2 door JK. Be aware that there is not any spare length in the harness so routing was important. Heat shielding is provided in the correct places. High quality plug and play.

Easy install. Completely plug and play. Works great

I was happy to find that the wiring harness was no problem to install even with my wider VersaHitch hitch. The problem with the installation document is that it only shows one connector behind the rear tail light; however, there are actually two connectors there. The new harness connector will fit into either one. Use the bottom connector. I first tried the top connector and everything worked except the right turn signal. Moving the harness connector to the bottom connector fixed the problem.
Questions
Nathan R.
Is there a plug and play way to wire a brake controller that maybe plugs in to the harness at the brake pedal to provide a brake controller with the power/ground, signal wire from brake pedal, as well as power to electric brakes (blue wire) after installing this 7 pin wiring?
Yes, installation requires some manual wiring because the Mopar 82210214AB 7 Way Round Trailer Connector for 07-18 Jeep Wrangler JK kit provides the rear-end 7-pin socket and basic lighting circuits, but it does not include a factory plug-and-play under-dash brake controller harness like full-size truck platforms have.
To fully hook up a traditional proportional brake controller, you will need to manually route and connect four essential lines:
Power (Black Wire): Must be run directly from the vehicle battery under the hood (protected by a 20A–30A auto-reset circuit breaker) through the firewall into the cab to supply constant 12V power to the controller.
Ground (White Wire): Securely grounded to a bare metal point or factory grounding bolt under the driver's side dash.
Brake Pedal Signal (Red Wire): Tapped into the cold-side brake switch wire under the dash (typically the white wire with a tan tracer on JK models) so the controller knows when you are pressing the brakes.
Electric Brakes Output (Blue Wire): Run from the brake controller's output back through the firewall and all the way to the rear to connect with the blue electric brake feed wire provided by the 7-way trailer connector kit.
Alternative Option:
If you want to avoid running traditional hardwired lines and cutting into factory under-dash insulation, many JK owners opt for a wireless proportional brake controller. It plugs directly into the USCAR 7-way socket at the bumper and communicates via Bluetooth with a smartphone app, handling the internal inertia sensing and brake actuation externally without requiring an under-dash module.

What exactly do I do with the blue wire? The install diagram shows that it is just zip tied up and not connected to anything. Is that correct or am I missing something here?
That is actually correct for most standard installations. The blue wire in the Mopar 7-Way Trailer Connector kit is the dedicated electric brake signal wire.
If the diagram shows it zip-tied out of the way, it’s because the harness provides the wiring for trailer brakes, but your Jeep isn't connected to a Brake Controller yet.
When Should You Connect It?
You only need to deal with the blue wire if you plan on towing a trailer that has electric brakes. To make those brakes work, you would need to:
Mount a Brake Controller (like a Tekonsha or Curt unit) near the driver's seat.
Locate the end of that "zip-tied" blue wire under the dash or near the battery.
Connect the controller's "Output" wire to that blue wire.

I was told it doesn't connect to the 4 pin harness. Instead it runs along side it. Does this mean your adding a 7 way to the existing 4 pin to use both of them? If so how how does 7 way work fully compared to a 4 pin or does it create a new separate connection all together with the 4 pin. So this way you can use either 4 pin or 7 way connection base on what your using?
Yes, you can use both. When you install the Mopar 82210214AB 7-Way Connector, it does not disable or replace your existing factory 4-pin harness. They become two separate, independent connections at the back of your Jeep, allowing you to choose whichever one fits the trailer you are towing that day.
How the Two Connections Work Together
Because the 7-way kit is a standalone harness, it creates its own "circuit" by plugging into the back of your taillights using T-connectors.
Your 4-Pin: Stays exactly where it is. It will continue to provide basic lighting (running lights, turn signals, and brakes) for small utility trailers.
The New 7-Way: Provides those same lighting signals PLUS three critical extra features that a 4-pin cannot handle:
Electric Brakes: The signal from an in-cab brake controller to the trailer.
12V Auxiliary Power: Constant power to charge a trailer battery or run interior camper lights while driving.
Reverse Lights: A signal to the trailer to turn on backup lights or disengage surge brakes.
