Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the trunk floor coverings, scuff panel, and hatch side liner to access the 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.


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 - C56391 Review

Speaker 1: Today, we're taking a look at the Curt T-Connector Vehicle Line Harness with a four full flat trailer connector. This part fits certain years of the Volkswagen Golf Ultrak. To ensure that this is a fifth year vehicle, or to double check that it's a fit, you can use the vehicle fit guide at etrailer.com.This unit provides a four-way flat trailer connector at the back of your vehicle to power your trailer's signal lights. It is compatible with five pull, six pull, and seven pull adapters. Adapters are sold separately. And it comes with a dust cap for the four way flat connector.

That way you can cover up the connection points when your plug's not being used. All the wires run to this black box. This is the included power taillight convertor. This ensures that your vehicle's wiring matches that of your trailer's. It connects directly to the battery through the wiring to avoid overloading your vehicle's electrical system.Now, this is constructed using Surface-Mount technology, offers consistent reliable performance.

What that does is it maximizes the trailer light yield and intensity while producing minimal heat and ensure superior operation even in rough road conditions. Now, this is designed to connect quickly and easily. All you need to do is locate the connection points in the rear cargo area, and plug in your connectors. One goes to the passenger's side; the other goes to the driver's side. And these are custom fit for our vehicle so these are gonna match up perfectly to the ports on the vehicle, and they snap.lock together for a nice, tight secure fit.So, as you have your T-connectors plugged in, you'll need to make a ground connection, that's your white wire with the ring terminal attached to it.

You need to get this one grounded at a suitable grounding location and you can use the included grounding screw to accomplish that. And then you'll need to mount the convertor box to a safe, out of the way location, and you can do that with the double sided adhesive foam tape provided in the kit.Next, you'll need to run the hot lead to the vehicle battery. The hot lead is the short black wire coming out of the box. This gets connected to one end of the bundle with one of the included bud connectors. The other end of the bundle runs to the vehicle battery, gets another bud connector attached to it, and connects to one half of your fuse holder.

The other half of the fuse holder gets a ring terminal attached to it, and gets connected to the positive post of the vehicle battery. Once you have that done, you can secure the excess or slack in your wiring with the included cable ties. And then once your installation's complete, the four-way connector will be stowed in an out of the way location within the trunk of the vehicle.Plenty of wiring here so you can extend it out the back when you need to use it, and then roll it up and tuck it away when you don't. It is recommended that you use a small amount of dielectric grease on all your electrical connections, like the plugs on the vehicle and the four plug connector itself. That's designed to help prevent corrosion to the connection points. That grease is sold separately and available at etrailer.com if you're in need of some.When it comes to the maximum amperage for the stop and turn lights, we're looking at five amps per circuit. And for the taillights, we're looking at 7.5 amps per circuit. The unit also comes with detailed installation instructions. This will help walk you through that whole process step by step.That's gonna do it for today's look at the Curt T-Connector Vehicle Harness with the four pole flat trailer connector.
