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.

Nicole was great but service from installers sucks. I called multiples and if you didn't order from them they wouldn't help. One I even spoke to before finalizing my offer cancelled doing service.

Literally plugs into the cars wiring harness at the brake lights. Directions are good but the video on this web site was great for seeing how things come apart. Product appears to be well made and performs perfectly.

The product quality can speak for itself, but i was extremely satisfied with the turn around time. i received my package in plenty of time for a planned camping trip. Also your customer service was top notch. i got a phone call checking my address for shipping and thought it was really great that someone was actually handling my order with care and it wasn't just me and a computer. So thanks alot. I'll for sure be using this service in the future

  • Is Curt Trailer Wiring Harness 56091 Compatible with LED Taillights

  • Recommended Trailer Hitch for 2013 Subaru Legacy
    If you do not know what trailer you are going to be towing you can still get a hitch because the trailer will require a ball mount in order to tow. For your 2013 Subaru Legacy I recommend the Draw-Tite # 36493 because the use of stabilizing straps with accessories are not a manufacturer's requirement in order to maintain the warranty like they are with the Curt hitch. Also, please keep in mind that according to the owner's manual of your 2013 Subaru Legacy the maximum you can tow is 1,000...

  • 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 Fit...

  • 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...

  • Recommended Towing Package for 2010 Subaru Legacy
    For a Class III trailer hitch by Curt that is a custom fit for your Subaru Legacy sedan, you will want the Curt Trailer Hitch # C13158. To complete your towing setup, you will also need the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 56091. I have included installation instructions and a installation video of this harness on a 2011 Subaru Legacy for you to check out. Then you will need the Brake Controller 7 & 4 Way Installation Kit, # ETBC7, to complete...
