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 interior trim panels in your rear cargo area.


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.


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. 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.

Today we're going to be taking a look at the Curt T-connector vehicle wiring harness with the 4-pole flat trailer connector. This product fits a 2010 to 2014 Subaru Legacy. To ensure that this is a fit for your vehicle, you can use the vehicle fit guide at etrailer.com. It provides a 4-way flat connector at the back of your vehicle to power your trailer's signal lights. That is compatible with 5-pole, 6-pole and 7-pole adapters. The adapters are sold separately and it comes with the dust cap for the 4-way flat plug.

That way you can cover up the connection points when it's not being used.The black box right here is the included tail light converter. This ensures that your vehicle's wiring matches that of your trailer's. That's constructed using surface-mount technology for consistent reliable performance. That's going to maximize trailer light yield and intensity while producing minimal heat. It also ensures superior operation even in rough road conditions.

Now, this unit is designed to connect quickly and easily. You don't have to worry about cutting or splicing any wires. Just locate your connection points in the rear cargo area and plug in your T-connectors. These connectors are custom fit for your vehicle so they're going to match up perfectly with the ports on your vehicle and they're going to snap lock together for a nice tight secure fit. One set goes to the passenger's side.

The other set goes to the drive's side of the vehicle. Once you have those connected, you'll need to make your ground connection. That's your white wire with the ring terminal attached to it. You want to get that grounded at a suitable grounding location using the included grounding screw.Then you can mount your converter box to a safe, clean, out-of-the-way location with the included double-sided adhesive foam tape. Once you have that done you can secure any excess or slack in your wiring with the included cable ties.

Once your installation is complete, the 4-way connector is going to be stowed in an out-of-the-way location within your cargo area. 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 4-pole connector itself. That grease is specifically designed to help prevent corrosion to the terminals. It is sold separately and available at etrailer.com. 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 5 amps per circuit. That's going to do it for today's look at the Curt T-connector vehicle wiring harness with the 4-pole flat trailer connector.

Ask the Experts about this Curt Custom Fit Vehicle Wiring

  • Comparing Curt and Tow Ready Trailer Wiring Harnesses for a 2010 Subaru Legacy
    Normally when there is a choice between a powered converter and a non-powered converter I go with the powered converter. The reason is that the powered converter, in this case # 118511, gets most of the power for the trailer lights from the vehicle battery. This protects the vehicle wiring and any potential electrical problems that could occur should there be a short on the trailer wiring. Either harness will work for you but the little extra effort needed to route and connect the power...

  • Does T-Connector Wiring Harness # 56091 Connect to the Battery on a 2011 Subaru Legacy
    The Curt Circuit Protected T-Connector Vehicle Wiring Harness, # 56091, does not require a power wire to the vehicle battery. It is a T-connector that plugs in line with the vehicle tail lights. Only the ground wire needs to be manually attached to a bare metal surface. I have included a link to the installation details for you to view.

  • Will Trailer Hitch # 75673 Fit a 2011 Subaru Legacy or Outback with Factory Dual Exhaust
    I spoke with my contact at Draw-Tite and he stated that trailer hitch # 75673 will fit the 2011 Subaru Wagon (except Sport) and All Legacy models. This would include dual exhaust models. There is some heat shield modification that will need to be done so the trailer hitch will fit properly. I have included a link to the installation instructions for reference and a video showing installation on a similar model. For the 2011 Subaru Outback (except Sport), you can use Tow Ready Custom...
