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.

    • Tail lights: 7.5 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your trunk behind the tail light housings. You will have to remove the trunk floor coverings and the rear and side scuff panels 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 trunk.


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.

Curious why you need to connect to the battery directly.

I'm from Canada and looked many places for this item. Sources in Canada did not have inventory, and it is hard to find a US based vendor willing to ship to Canada. The representative at etrailer was great. The process to find and purchase this item was easy, it was offered at a fantastic price and even with exchange, duty, and shipping, it cost less than the same item offered anywhere else - Canada/US. Shipping was quick with detailed tracking. Was a real pleasure doing business with this vendor. Highly recommend.

  • Will Curt Wiring Harness Operate Correctly When Installed on a 2023 Mazda CX-30
    When we spoke with our contact at Curt they said the only time they've heard of the Curt T-Connector # C86CR having issues is when one of the pins was loose on one of the connectors. They replaced the kit for the 2023 Mazda CX-30 and everything started working correctly. Once you purchase the wiring kit I recommend making sure all of the wires are properly secured in the connectors and then installing it. If you see that this issue happens to your setup then you can take advantage of the...

  • Troubleshooting Curt Custom Wiring Installation on 2021 Mazda CX-30
    Your 2021 Mazda CX-30 has the brake and tail light functions separated out and the Curt T-Connector # C86CR is designed to combine those circuits since trailers typically combine the turn and brake lights - the running lights should be on their own circuit. From what you're describing it sounds like you need to replace the Curt wiring kit but I would check the wires going into and out of the black box first. Here is what you'll look for with the wires going into the box vs the wires coming...

  • Parts Needed to Install 7-Way on 2022 Mazda CX-9
    To install a 7-way on your 2022 Mazda CX-9 you would first need to start with a 4-way like the Curt # C56338 which is a custom fit kit that doesn't require splicing. If the 7-way only needs to support trailer lighting function (not brakes) then all you need to convert it to a 7-way is the part # 37185 which plugs right into the Curt 4-way and is ready to go. If you need to operate trailer brakes the 7-way adapter you'd need instead is the # ETBC7 and a brake controller like the Tow Pro...
