Installation of Tekonsha T-One Connector

This custom-fit T-One 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 body harness up to your car battery and connect the wires per the included instructions.


T-One Connection Location Points Behind Tail Lights

Once installation is complete, the 7-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 7-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's 3-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine 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.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.


Installation of Tekonsha Brake Controller Adapter

This adapter splices into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located to the left of the steering column, through a grommet in the engine compartment.


This adapter is designed to plug directly into your electric brake controller after splicing into your vehicle's wiring. You can unplug and remove your brake controller at any time and securely stow it away.

Today we're going to take a look at the Tekonsha OEM replacement seven way vehicle wiring harness with the brake controller adapter. Now this is a custom fit part, it is designed to fit the 2015 and newer Ford Transit 350. This towing prep kit will replace your damaged factory seven way blade style trailer connector at the back of your vehicle. It will enable your truck to power your trailer signal lights and it is compatible with four pull, five pull, six pull adapters that we sell separately. The T1 connectors right here will connect very quickly and easily. Basically you just plug these connectors into the connection points behind your tail lights on the drivers side and on the passengers side. Then you'll have this white wire here, that you'll ground the white wire and then run this body harness up to your vehicle's battery.

These wires that are taped up is what'll connect to your seven way and these pigtail wires will connect to your break controller adapter. This harness does include this tail light converter to ensure that your vehicle's wiring will match that of your trailer. The break controller wiring adapter that they include will ease the instillation of your electric break controller. These wire end splices into your vehicle's wiring and on the other end you can see here will plug into the back of your electric break controller. This plug in is compatible with time delayed break controllers by Draw-Tite, like the Activator I, Activator II, Activator III, and the Tekonsha Powertrac. Also this plug in is compatible with proportional break controllers, Tekonsha Prodigy, Prodigy P2, Prodigy P3, the Primus IQ, and the Voyager. It does come with everything shown here.

It comes with a nice set of detailed instructions on how to connect everything and all your connections right in here. That should do it for the review on the Tekonsha OEM replacement seven way vehicle wiring harness with the break controller adapter.

2016 Ford Transit Connect

Installed on a 2016 Transit 350. The quality of this kit is pretty good, but there are two things that are problematic. First and most important, the connectors for the factory harness to do not line up with the actual Ford factory connectors in the taillights. I had to cut off one side of the prongs that should slide into the factory connector. Be sure to check first as only one of them is off - line it up and it will be obvious which one is off. Second, if installing this on a Transit without a factory harness there is no way for you to attach the 7 pin outlet. Does not come with the metal bracket to attach the outlet to your bumper. The length of the socket isn't going to allow you to really drill a hole and mount in the socket in the plastic. Last, there is a small box that goes in the drivers side cavity at the rear tailight that also has a ground wire attached. The length of the ground wire pretty much means you need to place it at the bottom of the cavity. They could lengthen that 6 inches so you can zip tie it high up in the cavity, but this is minor compared to points 1 & 2 above. Pay attention to the diagram for insetting the wires into the socket. Really easy as long as you orient it properly. They click in so don't force them - twist until it lines up. In the end it is cheaper than the Ford harness and a bazillion dollars less than letting Ford install it. 474978

Installed as expected with the exception of a missing part. I thought it was all inclusive but the bracket for the 7-way plug is not included. Got to the end of the install and realized it was missing and had to go back and order the bracket. Not a big expense but wish it was included so project can be completed. 611691

  • Troubleshooting Factory 7-Way Trailer Connection on 2016 Ford Transit T350
  • Because you know that your trailer cable was damaged, you will want to check each fuse that has to do with towing. You will want to check F4, F9, F12, F31, F43 as you stated, F45. Also relay F3, R8. After confirming these are good, you will want to use a circuit tester like # PTW2993 to test each function at the round factory harness just behind the connector.
