Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind your tail lights. To access these connection points, you will have to remove your rear scuff panel and trunk liner. 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 in your rear 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.


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.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56180 Review

Today, we're going to be taking a look at Part Number C56-180. This is the current T-connector, vehicle wire and harness with the four-pull flat trailer connector. This product is designed for certain years of the Cadillac ATS. It's going to provide your four-way trailer connector at the back of the vehicle. It's going to power your trailer signal lights. This is compatible with five-pull, six-pull, and seven-pull adapters. Adapters are sold separately and it's going to come with a desk app for the four-pull flat connector.

That way you can cover up the connection points when the plugs not being used. The black box is going to have the wire functions printed directly on it and they're going to be inline with the wires as they connect to the box or run through, so it's very easy to identify what wire is what function. Now, this is going to be your power tail light converter. This is going to connect directly to the vehicle battery through the wiring to avoid overloading your vehicle's electrical system. It's going to be constructed using surface bot technology, it's going to offer consistent reliable performance that's going to help maximize trailer light yield and intensity while producing minimal heat, and it's going to ensure superior operation even in rougher conditions. Now, one of the main benefits of a system like this is that it's designed to connect quickly and easily. All you have to do is locate the connection points in the rear cargo area. You're going to have two sets of connectors. Now, this is a custom fit vehicle wiring harness, or system, so it's designed to match up perfectly with the plugs on your vehicle.

The set with the green wire, that's going to go to the passenger side of the vehicle. The set with the yellow wire, that's going to go to the driver side. Locate the connection points. Plug in your T-connectors. Then you're going to need to make your ground connection. It's going to be the white wire.

It's already got a ring terminal pre-attached to it. You can make that ground to a nice, clean metal surface using an included self-tacking screw. Once you get that done, you're going to need to mount the converter box. They're going to include some double-sided adhesive tape. So, you need to get that peeled off, stick it to the back of the box, and stick it to a nice, clean out-of-the-way location. Once you have that done, you're going to need to run the hot lead to the vehicle battery. Hot leads going to be the black wire coming out of the box.

That's going to get connected to the bundled black wire with one of the included butt connectors. The other end of the black wire gets another butt connector attached to it, connects to one-half of the fuse holder, and the other half of the fuse holder gets a ring terminal attached to it and that connects to the positive post on the vehicle battery. It's going to come with a 10-amp fuse. It goes directly in the fuse holder and it's got a fuse cap to keep it all protected. Once you have all of that done, you can use the included zip-ties to secure any excess wires that you may have. Keeping them up and out of the way and then, once your installation is complete, the four-way connector is going to be stowed in an out-of-the-way location in the rear cargo area. Now, when it comes to the maximum amperage for the stop and turn lights, we're looking at 3 amps per circuit, and for the tail lights, we're looking at 6 amps per circuit. It's going to come with detailed instructions as well as a wiring diagram. So, those are going to help walk you through the installation process. Then, we also recommend that you use a small amount of di-electric grease on all your electrical connections, like the plugs on the vehicle and the four-pull connector itself, and that's designed to help prevent corrosion. If you need some of that, you can find it here and etrailer.com. It is sold separately. That's going to do it for today's look at Part Number C56-180.

The actual installation of the harness was easy regarding the 2 sets of dual plugs. My only criticism of this harness "kit" is there should be a printed warning/explanation of the tools required to complete the job. While I already owned a T20 Torx socket bit (to remove the 2 tie-down rings) and a solderless connector crimp tool to assemble the hot lead components together, not everyone may already be in possession of such tooling and thus not able to complete the job in a timely manner.
