Tekonsha Custom Fit Vehicle Wiring - 118461

  • Custom Fit
  • Trailer Hitch Wiring
  • Tekonsha
  • 4 Flat
  • Powered Converter

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Powered ModuLite reduces strain on wiring system.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection point in rear cargo area
    • Plug in connector
  • Includes ModuLite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 2.1 amps per circuit
    • Tail lights: 4.2 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in your rear cargo area, either behind the driver's-side tail light assembly or in the spare tire compartment. You will need to remove paneling to access this harness.


Once installation is complete, the 4-way flat 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 plug on your automobile and the 4-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 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 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.

Used this on my 2007 Subaru Outback to attach to a U-Haul trailer. Worked super well. Easy to install, fits everything correctly, and took a beating as I moved cross-country. Since then I have gifted it to a friend and they have not had any problems with it. 880662

2003 Subaru Forester

Arrived promptly after ordering. Was the right product for my 2003 Forester. Installation was simple; just a plug-in. I liked that the ground is integrated. Immediately fixed the burnt out converter on my original Subaru part (I have not yet completed testing my trailer for a short; not sure if that was the cause of the failure of my original part). It would have been nice for there to be a way to disconnect the wire from the converter to the flat 4-pole connector so it could be fed easily through the rubber nipple in the bottom of the spare tire well without cutting it (I had to cut it and re-seal it to pass the connector through). The wiring harness with wrapping is thicker than the unwrapped wires on the original, so I cut a groove in the bottom of the foam trim to allow space from the connector in the right rear area where it lives to the spare tire well. Even with these extra needs, installation took only 25 minutes or so. 782652

I was really pleased with how this mounted. The video instructions at etrailer.com were very helpful. As expected, it plugged into the Subaru connection perfectly, and it worked. My challenges were to find and choose the most weather-resistant place for a hole to run the wiring through (I chose an incision in a rubber plug, then put silicone on it) and non-interfering location to lay the wiring. I accomplished those things and had a good outcome. ( I have since sold the car, so can't comment on longer-term usage). 704538

  • Recommended Trailer Wiring Harness for a 2005 Subaru Legacy Wagon
    The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118461 is the best and only option for a 2005 Subaru Legacy Wagon. It does offer easy plug-in-play installation. The Tekonsha brand is the most reliable option we offer so you won't have to worry about any issues.

  • Where Is the Trailer Connector Plug On a 2005 Subaru Legacy
    The trailer wiring harness connector you will need to locate to install a trailer wiring harness like the T-One Vehicle Wiring Harness part # 118461 on a 2005 Subaru Legacy will be located in the rear hatch, near the spare tire well. That said, this model is a bit trickier than most so you will most likely end up removing more panels than needed to find it. It can be to the left or right of the spare tire well behind the panel or in between the seat and spare tire well under that panel.

  • Why Does Trailer Wiring for 2007 Subaru Forester Route Through Trunk
    Having the 4-way run out of the back hatch is actually the preferred method although it seems like it wouldn't be. Having the 4-way stored inside the cab of the keeps it protected from rain and moisture to prevent corrosion and keeps it protected from damage to the wiring or connector by rocks or debris that might be on the highway.

Instead, you would need to purchase each of the components separately.

  • Trailer Wiring Plug Location on a 1997 Subaru Legacy Wagon GT
    If your 1997 Subaru Legacy Wagon GT is not the Outback version, then you will not actually have a plug-in point for a trailer wiring harness. Non-Outback versions of the wagon must hard wire to install a 4-Way trailer connector, using a kit like part # 119179KIT. To hard wire the kit, you would use the included circuit tester to determine which wire carries each function behind your vehicle tail lights. You will also need to run a power wire to the positive terminal on the vehicle...

    The connector on the T-One Vehicle Wiring Harness with 4 Pole Trailer Connector, item # 118461, is a 6 pin connector and most likely will not work on your vehicle if the connector is a 10 pin connector.

The wiring harness was a simple plug in, by the left tailight, but a little tricky to get it to run out of the car. There actually was an oval rubber body plug up under the fender that you can just barely see from inside, and you can feel from outside, that I popped out and put a hole in for the wiring harness...

It is there you just have to search for it. Our...

    There are several potential causes for some trailer lighting functions to not work while others do.

  • Running Lights On Trailer Towed By 2006 Subaru Outback Wagon Stay On
    Because the converter box used on the # 118461 draws its electrical power directly from the battery, the fact that your trailer tail lights continue to illuminate after the vehicle ignition is shut off indicates that the converter box has shorted out. This is almost always caused by a short circuit somewhere in the trailer wiring, most likely the running light circuit.

An electric brake controller, like the P2, item # 90885, will also be needed to complete the installation.

The Hopkins version, part #33855, is rated for up to 8 amps and therefore is a bit heftier. I would suggest 33855, the higher amperage capacity may be useful depending on how many lights you have on your trailer or cargo carrier.
