Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
Powered Tail Light Converter with Surface-Mount Technology
A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

This wiring harness is great, all the connectors fit and watching the installation video helped save time and headache figuring out how to route the power wire to the battery. Plan for a few hours to install it, I installed mine while also installing the receiver hitch which makes access easier. Thank you etrailer!

Package was in the same bad as hitch, but everything was there, so what do I care. I’ve been using solder seal shrink wrap but end connectors. Heat gun melts solder and shrinks wrap. Routing power wire to battery is not for the faint of heart, but I knew what I was getting into. Service was fantastic. Ordered Tuesday and had it on Thursday!

2022 Jeep Grand Cherokee WL – new body
I installed the hitch and rear wire harness, I still need to run the 12v supply. I am a retired technician that worked at the Chrysler Tech Center so I am very familiar with doing this type of work. The installation took 1 1/2 hours and had no issues, the hitch and harness are excellent quality and fit perfectly. It is a lot easier to install the wiring with the facia removed. I guess that if I had to complain, they should have a place to screw the wiring module and ground on the hitch itself. The delivery was fast and free and much cheaper than the dealership, I would highly recommend them. Thanks etrailer!

It wouldn't work when I hooked it up. Tried working with etrailer and Curt to get it resolved, but neither of them helped. Curt was especially rude and kept saying I hooked it up wrong. I installed a Tekonsha kit and it worked just fine, so the Curt one was defective. I won't be buying Curt products anymore.

- Does Curt Trailer Hitch Receiver Fit 2022 Jeep Grand Cherokee WL New Body StyleWe do have a Curt trailer hitch receiver fit for your new body style 2022 Jeep Grand Cherokee WL (new body style). You were right on about the 4-flat wiring harness though, as it does fit your Jeep. The part numbers for the hitch and wiring that fit your '22 Grand Cherokee WL are the following: - Curt Trailer Hitch Receiver # C96NR - Curt 4-Pole Flat Trailer Connector # C27BR
view full answer... - Parts Needed to Add 7-Way to 2022 Jeep Grand Cherokee 4XETo add a 7-way to your 2022 Grand Cherokee 4XE you will need to start by adding a 4-way connector. The Curt # C27BR plugs into the connection points behind your tail lights, and will allow you to power the signal lights on a trailer. Once this is installed, you can add a 7-way using the # ETBC7. This kit comes with an adapter, wiring, breakers, and everything else required to perform the installation. We have both written instructions and installation videos for this process which I have...
view full answer... - Compatibility of Curt C51180 Echo Wireless Brake Controller With 2021 Jeep Grand Cherokee LA brake controller isn't a vehicle specific item, they can be installed on just about any vehicle. If your 2021 Jeep Grand Cherokee L has a functional 7-way trailer connector at the rear bumper, the Curt # C51180 Echo wireless brake controller would be a plug and play installation, no other parts would be needed. If you don't have the 7-way trailer connector, you'll need a functional 4 pole trailer connector which would be provided by the # C27BR trailer wiring harness. Once that's installed,...

The adapter requires its own power wire to the battery. You can't just use the wire that's already run because the circuit ratings are not the same and they'd both be pulling power at the same time, you will very likely damage the converter and or blown some fuses if you wired the adapter and...

The Curt Trailer Hitch Receiver part # C97JR is what I recommend as it offers a bolt-on fit with no drilling required.

That said, not to worry as we have a video which shows you how to do this from start to finish and I have attached that for you below. The installation time we estimate...

view full answer... - How To Add a Trailer Brake Controller To a 2022 Jeep Grand Cherokee LI do have an option for you but there are no trailer brake controller provisions on a 2022 Jeep Grand Cherokee L, therefore there are no plugs behind the dash to plug a brake controller into.
