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 trunk floor coverings and rear scuff panel and pull back on the trunk liner to access these connection points. Once you've plugged in the T-connector, run the hot lead 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.

First harness had issues for my model of car. They promptly replaced and works well. Very satisfied.

I did receive the hitch. I installed it right away. Great product, easy to install, looks great! I haven't installed the wiring harness yet but I don't expect any problems!




by:

Adam far exceeded my expectations!! I had an immediate need for a part. He not only delivered but delivered before promised!!! I have bought 3 trailer hitches a trailer and multiple smaller items from etrailer.com and we have always had the best experience.




by:

On the hybrid model this was so easy since the battery and all of the connections are in the same place. Plug and play. It probably only took about 10 minutes to install. No issues with the installation and the lights on trailers work great.

Excelent kit
Works perfectly.
My
MKZ is a hybrid and has the battery in the trunk so wiring even easier than expected.
The YouTube video tutorials are a great help for the first time installing one of these.
I really like the isolated design. Great product!!

  • Troubleshooting No Brake Lights on Curt C56258 Harness on 2014 Lincoln MKZ
    It sounds like you're not getting a signal on the brake light circuit anywhere on the plug of the Curt # C56258 and there are a few things you can check out here. I would start by just making sure that the ground wire is secured to a paint and rust free spot on the vehicle's frame; this all could just be a situation where the ground isn't sufficient to power the brake lights. Next, you'll want to start testing out the wiring behind the harness on the Curt # C56258 and then where it plugs...

  • Trailer Hitch Recommendation for a 2014 Lincoln MKZ Hybrid
    I would recommend you go with a Class II hitch over a Class I hitch. The capacities will be higher and more hitch accessory options will be available. For example, with a Class I hitch you can only carry up to 2 bikes, whereas with a Class II you can carry up to 4. I attached a help article that covers the differences between hitch classes for you to check out as well. For a hitch I would recommend the Curt Hitch part # C12091. This is a Class II hitch that would work well towing a trailer...
