Quickly and easily install a 4-way trailer connector on your Jeep Grand Cherokee L with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

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.
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.

The quality is great! And all the parts were correct and arrived fast!
Install took a little longer than 2.5 hours as my husband and son had to redo the wiring. They did follow the video which helped a lot!
Works as described and the install videos were an amazing step by step. If I could give 4.75 stars i would because the power wire was short about 6 feet and I followed the video to a T.
Installation was smooth since I had to take off all the body cladding to install the trailer hitch.
Exactly what I wanted. A quality harness that is built to last.
Have bought two hitches from etrailer. In both cases, the right product and great support. For sure, I will buy the hitch from my next car here.
This is a well made wiring harness. Install is a bit involved but everything fit perfectly.
Great products at competitive prices. Video was very helpful! Everything exactly as promised. I am a returning customer.
Harness worked just as explained in the included install specifications.
Awsome , fast delivery and great videos for installing
I just received and installed a class 4 hitch on my 2022 Grand Cherokee Laredo L and as usual it was easy to install, and as usual the hitch is top notch. This is my 5th hitch I've purchased through the years and I will purchase all my hitches from etrailer. In fact I'm about to purchase number 6,thanks for the great products.
Great wiring harness. Easy to install when installing a trailer hitch and quality made.
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!
Still working without issues. Installation was just as the video displayed. Solid product one year on!
Great hitch fairly easy to install. About 4 hours. Nice step by step instructions and good videos on line. I highly recommend. Just take your time step by step and you will succeed.
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!
Joanne K was a wonderful help. Very knowledgeable and found exactly what I was looking for. Helped me purchase 2 trailers and arrived sooner than expected. Hope to be purchasing more soon. Thanks again
Good kit, works perfectly. Running the cable to the battery is a pain but really not too bad since you can fit under the Grand Cherokee without having to lift it.
Fast Service
Excellent wiring harness. Easy to insta ll.
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!
