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. 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.

Install was easy and instructions were great! I have used it almost weekly for a year and it has performed flawlessly!



by:

Failed after 20 months of minimal use. The trailer lights stay on even when the Bronco is off (and no vehicle lights are on). I was told the warranty is one year and I can buy another one. I expected this to last longer and will try to find another option.

Mike, I have heard of this before. When it happens it means that the harness has experienced an overload and generally is not fixable. It is unfortunately that it happened past the warranty time frame for the harness. I recommend taking a look at part # TK33VR if your 2022 Ford Bronco does not have LED tail lights or part # TK99VR if the Bronco with LED tail lights. We tend to see it happen less with the Tekonsha branded harness.



by:

Quick delivery; clear instructions.

I installed this on my Ford Bronco Base. The hardest part of the install is getting into the tail light assembly area. Overall it is a straight forward install. I've been using it for a year now with no issues. Towing my boat and off road camping trailer. It has been on long road trips and survived getting bounced around off-road and continuing to work with no issues.

2021 Ford Bronco

Easy installation and works fine.



by:

very well kit...fit just as instructions..wish there was a place to get power in rear instead of running wire all the way to battery, but well made kit



by:

Great part, easy install quality fit



by:

Works as expected



by:

Perfect fit



by:

I ordered my trailer towing harness and it arrived before I expected it to. The quality seems top notch. Installation was easy and it functions perfectly.



by:

Harness/adapter works fine. No issues.



by:

Wrong product for my needs; sending it back; explained intended application and your sales person (as well as myself) didn’t recognize it;



by:

This was a good product, install went smoothly on my 2dr Base. All needed accessories were included, and my lighting is working well.



by:
2023 Ford Bronco

My nearby autobody shop is installing this today. Plug & play should make it easy for him.



by:

Great product. Easy to install



by:
2022 Ford Bronco

The wiring harness was easy to install. The connectors fit the factory connectors without any issue. There were plenty of crimp fittings, wire, and zip straps, although I used more zip straps than were probably necessary. I can’t say that Ford made it easy because it was tight getting the wires pulled through.



by:
2022 Ford Bronco

They instructions are decent but I still opted to watch snippets of a YouTube installation as well to help routing of specific wires. Seems to be an excellent product and installation was easy taking about 1.5 hours. Would recommend.



by:
2022 Ford Bronco

the videos should show that the 4 little black screw/plugs [ holding the inner light plastic cover ] can be pulled out like a bad tooth!



by:

Harness was made by Curt. What can you say, Curt always makes the best.



by:

Excellent. Quality product.



by:
2022 Ford Bronco

Install it myself with youtube help, after installation use the hitcher tester, everything work accordingly.

  • Correct Curt Wiring Harness for 2023 Ford Bronco with LED or Halogen Tail Lights
    It does matter if your 2023 Ford Bronco has LED lights or not, but once you figure that out it's just a simple matter of getting either of these harnesses: - With LEDs # C42WR - Without LEDs # C87BR Both options plug in behind your tail lights and then draw power from the vehicle battery via the included wiring lead. I also recommend picking up the mounting brackets # C57202 and # BK4F so you can secure the 4-Way connector next to your hitch receiver for easy access.

  • Differences Between the Curt & Tekonsha 4-Way Wiring Harness For Incandescent Lights On 2022 Bronco
    You are correct, both the Curt # C87BR and Tekonsha # TK33VR harnesses will both fit your 2022 Ford Bronco with incandescent tail lights. Both are custom fit and will connect in line of your factory tail lights. They both include the additional wiring needed to run a power wire to the battery to power the module. As far as differences go, in my experience the Tekonsha harness is more reliable over time. While both harnesses have a 1-year warranty the Tekonsha seems to have a more durable...
