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 tail lights. You will have to remove the tail light assemblies to access this 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 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 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.


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.

Received my wiring harness along with my hidden hitch from Etrailer. Very happy with the yow assembly but the wiring harness was a little more difficult to install then I thought. On the 2010 Ford Trandit connect XLT right rear tail light assembly has no access point to run the harness thru so you have to remove the rear passenger side tire and fender well Caling to be able to drill a 1" hole thru the wall that access the tail light assembly. This is time consuming let along if you don't have a drill or large enough but to drill with them your screwed. Luckily I had the tools for the job. Another customer might not be so fortunate. I think some Ford Transits are different when it comes to the passenger side rear tail light assembly (rubber Grommet) access, others might have the access point so you don't have to spend 2 + hrs to install. All in all I'm very pleased how it turned out.

What a great product. Easy installation, watch a few vids on how to do it. Took me 1 hour to do it by myself with help of some Jack stands and Jack.

I was disappointed with this item, and expect more from Curt. Unlike the more expensive brand, there are no plug connections on the wires on the flat 4 so it won't fit through the driver side opening to pass to the passenger side. I had to cut the four wires and then butt connect on the underside of the vehicle. Had to make a trip to the auto parts store for heat shrink but connectors, and put in the extra time. Instructions were also lacking on where to feed the wires out of the taillight bucket. Decide if you have more time than money when thinking about purchasing this item.



by:

The trailer wire harness assembly fit perfectly. Not confusing to install, either. It wouldn't work without connecting the converter to the battery so I had to connect that and string the wire along the frame all the way to the back to make it work right. No problems at all.

This was an easy installation. I say that as someone who has experience with electrical wiring and hiding wires. I would say difficulty is about a 3 in the real world. The included instructions are good enough and photos are accurate.

received the wiring harness quickly and it was in good condition waiting on a little warmer weather to install it

I received the T Connector kit within just a couple of days from my order. I was very pleased with the speed of the shipment. I haven't installed the kit yet, but it looks fine and I anticipate it will mork great.

Instead of running the power line up to your battery, consider using the rear 12volt power source if you have one. My Transit was a Wagon version and did have one.

  • Is Exhaust Lowered To Install Draw-Tite 75678 Class III Trailer Hitch on 2010 Ford Transit Connect
    According to the installation instructions, lowering the exhaust isn't required during the installation of the Draw-Tite # 75678 on a 2010 Transit Connect. The instructions do call for the spare tire to be lowered to gain access to the frame and then raised back up into position after the install is complete. Installation of the Tekonsha Custom Fit Vehicle Wiring, part # 118585, is not too bad. The unit simply plugs into the factory connectors of the tail lights on each side of the vehicle...

  • Comparing the Curt T-Connector 56090 and Tekonsha T-One 118585 for a 2010 Ford Transit Connect
    The Curt T-Connector Vehicle Wiring Harness part # 56090 and the Tekonsha T-One Vehicle Wiring Harness part # 118585 are both fits for your 2010 Ford Transit Connect. They are essentially two different manufactures version of the same product. The purpose is the same as well as the install. The only difference is really in terms of quality and that edge goes to Tekonsha as we have less issues with the T-One than we do with the T-Connector but both will work just fine for you.

  • How to Remove and Re-Install Wiring Harness Grommets on a 2010 Ford Transit Connect
    The grommets you are inquiring about are located inside the sheet metal hole behind the vehicle tail lights. You will need to remove the grommet on both sides of the vehicle. On the drivers side pull the grommet out, using a dull edged object to help un-seat the grommet, and make a slice in it, being careful not to damage the existing wiring, large enough to route the 4-Way connector and green wire down through. On the passengers side pull the grommet out and route the green wire up through...

  • Left Turn Signal Not Working on Curt Vehicle Wiring Harness for 2013 Ford Transit Connect
    It sounds like an intermittent ground problem that is potentially causing both issues. What I recommend is to try moving the converter box ground to a different location. You may need to scrape away paint to get to bare metal for the best ground. Also make sure that the fuse in the power wire is fully inserted and that nothing is pinching any of the converter box wires. I have also included a link to troubleshooting wiring for you that should also help.
