CURT Custom Fit Vehicle Wiring - C27BR

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your vehicle 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.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


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.


Curt SMT Circuit Boards

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.

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!

2023 Jeep Grand Cherokee L

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.

This harness is great to use. It's super simple to hookup even for the novice person. Hook-ups are super simple.

Ordered a hitch and wiring harness for our Jeep Grand Cherokee from Robert over the phone. Our normal towing vehicle broke down and we were in a bind to get this installed for an upcoming trip. Paid extra for quick shipping and it arrived even faster than expected, in fact I was able to complete the installation in less than 24 hours from the time I ordered it from Robert. Fast professional customer service from Robert and etrailer! Thank you!

  • Trailer Wiring Harness For 2023 Jeep Grand Cherokee L
    We do indeed have a trailer wiring harness that fits your 2023 Jeep Grand Cherokee L; I verified directly with the manufacturer for you that the correct fit for your Jeep is the following: - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C27BR

  • Troubleshooting Error Codes on 2022 Jeep Grand Cherokee L After Installing Curt T-Connector Wiring
    If the Curt T-Connector Vehicle Wiring Harness # C27BR was installed correctly on your 2022 Jeep Grand Cherokee L you shouldn't be getting any of those lights. The only time you would see those lights is if the kit wasn't installed correctly or if the T-Connector is malfunctioning. The tees in this wiring kit let the OEM circuits flow directly through and basically just use those circuits as triggers for when to send power back to your trailer wiring. The trailer wiring is powered via...

  • Trailer Wiring Solution for 2023 Jeep Grand Cherokee L with Tow Package
    Due to how it installs you can still use a trailer wiring kit for vehicles without the tow package on vehicles with it like the Curt part # C27BR. This installs by plugging inline with the taillight connectors which is same between both types of vehicle configurations so this would be what you would want.

  • Trailer Hitch and Wiring that Fits 2022 Jeep Grand Cherokee 4xe
    I checked with Curt for you and confirmed the Curt Trailer Hitch Receiver part # C24BR as a fit for a 2022 Jeep Grand Cherokee WL 4xe. This hitch is an excellent option because it installs behind the bumper so it won't even be visible while not in use for a factory appearance Then for trailer wiring you'd want the Curt # C27BR that you referenced and you'd be set.

  • 5-Way For 2023 Jeep Grand Cherokee L
    There is not a direct wire kit for a 5-way for any vehicle, including your 2023 Jeep Grand Cherokee L, so what you'll need is a 4-way (if you don't already have one) and a 5-way adapter, which are the following part numbers: - Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C27BR - Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036 The 4-way will give you all the functions for your trailer lights, and the 5-way adapter will splice into your Jeep's reverse lights.

  • Recommended Trailer Wiring Harness For A 2021 Jeep Grand Cherokee L
    The connectors for a 2021 Jeep Grand Cherokee and Grand Cherokee L will be different, so the Tekonsha # 118727 will not be correct for your vehicle. With that said, you will need the Curt Vehicle Wiring Harness # C27BR for your 2021 Grand Cherokee L. This will be mostly plug and play for the install, but you will need to run one wire up to the battery for needed power. I included an install video we have of this being installed on a 21 Grand Cherokee L for you to check out as well.

    The etrailer Trailer Hitch item # e27KR weighs 46 lbs. It is custom fit and attaches to your 2022 Acura MDX with included hardware and does not require any drilling or welding. This hitch has a 2" x 2" receiver. I have linked an installation video below.

  • 4-Way Wiring Harness for 2021 Jeep Grand Cherokee L
    I apologize for any confusion or frustration over this. What you saw is the TK39VR installation video which I attached below. The parent company of Tekonsha recently changed which has resulted in supply issues. This means some parts, like the wiring harness, currently aren't available. As of March 2023 we don't know when they will be back. The Curt # C27BR you looked at has the same design and installation process. The T-connector will plug into the connection points behind your tail lights....
