Tekonsha Custom Fit Vehicle Wiring - 118647

  • 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. 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
    • Locate connection points in trunk
    • Plug in T-connectors
    • Run hot lead to car battery
  • 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: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your trunk, behind the tail lights on both the driver's side and passenger's side. You will need to remove the rear threshold panel and push back the felt liner to access the harness.


T-One Connection Location Points Behind Tail Lights

Once you've plugged in the T-connector, run the hot lead with the attached fuse holder to the car battery. Connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed in the driver's-side storage compartment in your trunk when not in use.


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.


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.

I initially ordered the incorrect wiring harness for my car. My fault completely. An email and short phone call later, I had excellent return instructions and the correct harness on the way to me. Great customer service. Quick delivery and credit on my credit card. Received the correct harness and it fit perfectly. Good, easy to follow, written instructions included in the package. 747372

Good product, easy to install. No need to run power to front of car, as Volvo has a fuse box underneath floor in rear. Just wired power there. 600150

Product works as advertised. The install was a challenge. Don't waste an evening trying to run the power wire inside your V60 and out through the firewall. The engine compartment is too tight. The conveniently located plug located under the the dashboard on the drivers side is behind the battery box and cabin filter. Just run it up the outside and go do something fun. 296211

  • Recommended Trailer Wiring for a 2016 Volvo V60
    To add a 4-Pole connector to your 2016 Volvo V60 I recommend going with the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118647 because we have found Tekonsha to have the most reliable electronics. This kit will simply T into the tail lights on your V60. You will also need to run the included Black wire up to your battery for power. This will keep the lights on your trailer from affecting the lights on your V60. I was able to look up and see that the...

  • Availability of Trailer Wiring Harness for 2015 Volvo S60
    Currently, there isn't a plug and play trailer wiring option for your 2015 Volvo S60. You'd need to go with a hardwired option like the Tow Ready # 119190KIT. I've checked with Tow Ready, and they confirm the recommendation. I've linked you to an install video showing the harness being installed on an older XC90. The specific procedure would be different on your vehicle, but the procedure for testing to identify which circuit carries which function would be the same. The # 118647...

  • How to Install a Brake Controller on a 2016 Volvo V60
    The best way to run the wires for a brake controller through the firewall on your 2016 Volvo V60 is to look for the large rubber grommet that feeds the wiring harness from the cab into the engine bay. This harness/grommet is usually located by the intermediate steering shaft but could be elsewhere. Basically, once you find the harness you will want to poke a hole in the rubber grommet and feed the wires through with some sort of leader. Unfortunately, we don't have a video of this as we...

  • Recommended Trailer Hitch and Wiring for 2018 Volvo V60 R Design
    Starting with the trailer hitch I recommend the Draw-Tite Class III Max Frame Receiver Hitch # 75916, which is confirmed to fit the R Design edition of your 2018 Volvo V60, because it is the highest rated unit available for your vehicle. This will provide you with a 2 inch receiver opening, will use existing holes in the Volvo's frame for a no-drill installation, and features a clean hidden-crosstube design where only the receiver will be visible (see attached photo).

I have included a picture that shows where the trimming needs to be. If you want to use the hitch for an accessory such as a bike rack or cargo carrier then you have to make sure the accessory is rated for use with a Class II trailer hitch.

  • Can I Tow with my 2019 Volvo V60 with Class 2 Hitch with 1 1/4 Receiver
    The issue with upgrading your current hitch is that none of our manufacturers can confirm fitment for the 2019 Volvo V60-although all of them could verify fit on the 2018 model. That being said, with a trailer under your vehicle's 1650-lbs towing capacity, you will have no problem towing on your existing hitch receiver. In order to tow with your existing hitch you need a ball mount, hitch ball and wiring harness. In order to determine which ball mount rise/drop is correct for you, I've...

  • Does Impact Bar Need To Be Removed When Installing Trailer Hitch On 2015 Volvo V60

    The Draw-Tite Max-Frame Trailer Hitch Receiver # 75916 is a confirmed fit for your 2015 Volvo V60 and will work great for you.
