Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, on both the driver's and passenger's sides.


Once installation is complete, the 5-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 5-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.

Overall, I think that the product works well and is relatively easy to install. My only complaint is that it requires the user to drill a self tapping screw for the ground wire but the ground wire length coming out of the harness is too short to attach to a ground point if the device is installed per the instructions. My preferred location for installation (which is concurred by the instructions) is behind the driver's side tail light. This doesn't present any easily accessible spots for grounding and the ground wire as provided isn't long enough to reach a good ground point. I would prefer to keep the device behind the tail light because this is the best protected from the elements. Hanging it under the vehicle exposes it to all manner of elements and potential snags.

This is a relatively minor issue but is still an issue, nevertheless. Overall, this is a good product that is easy to install.

Still going strong after a year. No complaints.

This harness installed quickly and easily. For the premium price, it should have included the optional mount bracket. I added a wire loom to the last couple of feet for protection. I dislike the price, but didn't want to splice into my trucks wiring with a universal harness. Shipping was fast. (Be sure to mount the box behind the left taillight before screwing down the ground wire. If not, you may not have enough ground wire to allow the box to reach up behind the taillight.)

This is to praise the service I received from etrailer.com. They phoned me after I placed my order to confirm my shipping details. My product was shipped ONE day after my order was received! I loved their tracking link. It was a direct link from within my shipping notification, not a redirect to a shipper's site where one has to enter a tracking number. And the coolest part was the map that was displayed with the shipping location, my location and a cute little truck on the way. Loved it! Thanks for a great experience, I wish all sellers websites and customer service departments were as good as etrailer.com!!!!!

I have not used the product yet but I have installed it my vehicle. Since I had a 4 pin already installed the installation was quite easy.

My dissapointment is with the lack of any tape or sleeving over the wires - epecally the wire run up to the 5 pin connector where it could easily get chafed over time. I will be adding some protection there on my own as my previous 4 pin came with it.

The Trailer hitch and harness came within a few days.
Everything is installed without a problem.
I plan to test it out tonight.
Thanks

Product works well. Double sided tape on back of “controller” let’s go over time regardless of how clean vehicle surface is before installation.

  • Trailer Wiring Harness Recommendations For a 2005 Toyota Tacoma
    It sounds like you have an aftermarket trailer wiring harness. Whether it is aftermarket or factory, that clicking noise you hear and the trailer lights not working indicate that there is a problem internally with the converter and it will need to be replaced. There are several options and I have included a link to them for you. The Curt harness you have referenced, # C56513, is a fit but this harness has a 5-Way flat trailer connector. A 5-Way flat is most common on boat trailers that...

  • Trailer Wiring Harness Recommendation for a 2013 Toyota Tacoma
    For a trailer wiring harness that will fit your 2013 Toyota Tacoma I recommend # 118496. It plugs in line with the vehicle tail light wiring and provides a 4-Way flat connector at the rear of the vehicle. I have linked a video showing an example installation for you.

  • Is Wiring Conduit a Good Idea When Running Wiring of Roof Vent Fan Through Ceiling
    The flexible plastic tube you are referring to is known as wiring conduit and is a really smart idea to protect wiring. Especially if the wiring will be difficult to access once the trailer is put together like what you are doing. I'd recommend using some 3/8 inch diameter conduit like the part # 39035 when running the wiring just as an insurance policy to keep the wiring more protected.

  • Installing 5-Way Trailer Connector on 2000 Jeep Wrangler for Trailer Reverse Light
    I have a solution that will allow you to install a 5-way on your 2000 Jeep Wrangler but since the 5-way style of trailer wiring is one of the least common setups there isn't a custom fit 5-way for your vehicle. You'd want to install the 4-way that you ordered and then convert it to a 5-way with a 5-way adapter like part # 20036. Basically with this you'd just plug it straight into the 4-way and run the additional blue wire to the reverse light circuit of your vehicle and you'd be set....

  • Troubleshooting Trailer Lights Not Working Properly with New Lights and Wiring
    While it is very possible for the converter on a Curt T-Connector like part # C55513 or # C56513 for your 2008 Toyota Tacoma to go bad, it is important to do some troubleshooting before replacing parts because if the problem isn't the converter then you're out money and time spent on the new wiring harness. To determine if the converter on your T-Connector is bad or not you need to take a circuit tester like part # PTW2992 and start off by testing the connector for signals (see attached...

  • Adding a 7 Pole to my 1997 Toyota T100
    Yes you can use the Curt T-Connector Vehicle Wiring Harness with 5-Pole Flat Trailer Connector part # C56513 to use as the basis for your 7 pole connector. Once this is installed I recommend cutting the connector off and using heat shrink butt connectors like part # DW05744-10 to connect to the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires part # ETBC7. This simply eliminates a connection that could eventually fail. At that point just...

  • Recommended 5-Pole Flat Trailer Connector To Replace Damaged Connector
    If the 5-way connector you have is installed on the vehicle you can use part # HM37908. You would just cut the connector off of your vehicle and splice the # HM37908 with the length of wire you need. You can use butt connectors like part # DW05744-5 to connect the wiring. If the connector is on the trailer then you can replace the damaged connector with part # HM47910.
