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 some bumper fascia, interior paneling, vent covers, and 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 your vehicle runs on a multiplex wiring system, the wiring needs to be converted to be 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 hardwires to the body harness that is included in this kit. Just connect the black wire from the brake controller adapter to your car battery, and connect the white wire to a suitable ground. The remaining wires can then be easily spliced into the body harness with the included butt connectors.


This adapter is designed to plug directly into your electric brake controller. Because the harness does not hardwire to your controller, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

Speaker 1: Today we're taking a look at the Tekonsha OEM replacement vehicle wiring harness with the brake controller adapter. This product fits a 2014 to 2015 Freight liner Sprinter and Mercedes Benz Sprinter. It also fits a 2016 to 2017 Freight liner Sprinter and Mercedes Benz Sprinter 2500 and 3500. inaudible 00:00:24 double check or insure that this is a fit for your vehicle. You can always use the vehicle fit guide which is located at Etrailer.com.This is designed for vehicles that do not have a factory tow package but it can also be used as a replacement kit for damaged tow packages. This towing prep kit puts a seven way blade style trailer connector at the back of your vehicle.

It enables your vehicle to power your trailer signal lights. It is compatible with four-pole, five-pole, and six-pole adapters. Adapters are sold separately.It does come with the taillight converter which insures that your vehicle's wiring matches that of your trailer's. The wiring adapter which is located right here, eases installation of your electric brake controller. The wire ends connect to the included body harness and vehicle battery.

The other end, that little plug right there, goes into the back of your electric brake controller. It is compatible with time-delayed brake controllers like the Draw Tite activator one, activator two, and activator three as well as the Tekonsha Power Track, and it's compatible with proportional brake controllers, like the Tekonsha Prodigy, the Tekonsha P2, P3, the Tekonsha Primess IQ, and the Tekonsha Voyager.The T1 connector is very quick and easy to install. It's basically designed to plug into the connection points behind the vehicle's taillights. It uses custom fit connectors so there's no cutting or splicing necessary. They do match up perfectly with the connection points on the vehicle and they snap and lock into place for a nice tight, secure fit.Once you have those connected, you will need to make a ground connection which is your white wire.

It has a ring terminal pre-attached to it, hardware's included to get that grounded. Then you'll need to mount the convertor box to a safe, out of the way location. You can do that with the double-sided adhesive tape provided in the install kit or the hardware bag, but once you have all that done, basically what you'll need to do is run the body harness up the vehicle battery. Now you will have some wiring connections to make. You're going to have to wire this in.

It's got the terminals right there on the back. It does come with detailed installation instructions to help walk you through the whole process, step by step.You're going to have to tie in the wiring that will run back from the brake controller which is at the front of the vehicle. You'll need to do that but it does come with all the necessary wiring. It comes with all the necessary fuses, circuit breakers. Comes with all the necessary connectors so you've got some quick splice connectors, ring terminals, heat shrink butt 00:02:45 connectors and so on, so it does come with everything you need for the installation. You'll run the body harness up to the vehicle battery. Then you'll make all your connections. You'll need to tie in, obviously the brake controller wiring as well. Once you have all of that done, the seven way will be stowed beneath the vehicle near the trailer hitch. Now, we do recommend using a mounting bracket to keep this secured and easily accessible near the hitch. Mounting brackets are sold separately and available at Etrailer.com.It's also recommended that you use a small amount of dielectric grease or terminal grease on all of your electric connections like the plugs on the vehicle and the seven-pole connector itself to help prevent corrosion. Again, the kit does come with everything that you need for your installation, wiring, fuses, circuit breakers, connectors, hardware, and so on. When it comes to the maximum amperage for the stop and turn lights, we're looking at 4.2 amps per circuit. For the taillights, we're looking at 7.5 amps per circuit.That's going to do it for today's look at the Tekonsha OEM replacement vehicle wiring harness with the included brake controller adapter.

Best sprinter wiring kit. Do yourself a favor and save time and hassle with this kit. Also seems much better at blocking corrosion to sensitive areas (than diy) as you don't need to splice anything outside of the vehicle. 757162

I used this wiring harness on my 2014 Sprinter. The instructions for this product was spot on, and i very much liked how it was plug and play, no wire splicing. The harness plugged right into the factory harness just like it came from the factory. It did take a little bit on my part fishing the wires thru the cavity wall supports and keeping it neat and organized, but overall 5 stars. Sorry, i forgot to take pics. Thanks etrailer 749367

  • Connecting a Brake Controller Red Wire on a 2017 Mercedes Sprinter 2500
    Your 2017 Mercedes Sprinter 2500 may actually have brake controller port or wiring harness that you can use to install a brake controller. I have included a link to a video that may help. It is on a slightly older Sprinter but can be used as a guide. The 2006 to 2018 are part of the same generation. If the van has a third brake light (CHMSL: center high mount stop lamp) and it is the only thing on that fuse you could use it to attach to the red brake controller wire. The white ground...

    Yes, for your 2016 Mercedes Benz Sprinter 2500 the Draw Tite hitch part # 75549 is a fit and my recommendation for your application as it has the capacity you need and installs easily as well. I attached an install video for this for you to check out as well.

  • Does The Spare Tire Need To Be Removed to Install Curt Hitch On 2019 Mercedes-Benz Sprinter 2500
    According to Curt you will not need to remove the spare tire when you install part # C13388 as long as it is a standard spare tire size. As long as the 2019 Mercedes-Benz Sprinter 2500 is a 170 or 144 inch wheel base, standard bumper and is not a passenger van this hitch is confirmed to fit without removing the spare tire.
