Tekonsha Custom Fit Vehicle Wiring - 118656

  • Custom Fit
  • 4 Flat
  • Trailer Hitch Wiring
  • Tekonsha
  • 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-connector
    • Run hot lead to car battery
  • Includes ModuLite that 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: 4.2 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 some of the felt lining to access the harness.


Once you've plugged in the T-connector, run the hot lead with the attached fuse holder to the car battery, which is also in your vehicle's trunk. 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 your trunk.


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. 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.

In my humble opinion, connecting the extra black wire to the yellow fuse and the yellow fuse to a positive connector was a bit clunky. The yellow couplers are not really all that great as far as keeping the wires connected. I had to use electrical tape and zip ties to make sure the couplers stayed together with the connecting wires. In the future, I'd consider already having those wires solidly connected. I see no point in making the customer spend time connecting those wires. The instructions and pictures left much to be desired as well. The best instructions i found were on youtube and it was a dodge charger not a challenger (but they are similar enough to get the job done). Other than that, I'd say everything else went as planned.

Has worked flawlessly. Was easy to install. Wish the plugin to the trailer was a little longer harness. Minor objection. Using set up to haul 4Ă—8 utility trailer for light loads of lumber and wood for my woodworking hobby. Would buy again.

I ordered a wiring harness for my 2019 Dodge Challenger SRT Wide Body. Instructions were excellent. Installation was easy. Everything went as planned. Great company to deal with.

The only two things that are keeping this from 5 stars; the battery power in is a short cable; they had the foresight to give you another pigtail to extend it but then you are left with 2 splices in the positive cable. It would make much more sense to just manufacture the thing with a foot long battery cable rather than splicing pieces after the fact. Other than that I’m pleased.

Very easy install. Plug and play . Detailed instructions.

As "plug n play" as can be, though you will need a stripper and crimping tool for the power and ground leads.

  • Parts Needed for 2017 Dodge Challenger to Tow Trailer
    It's a combination of a few things, but the only people who will be able to give you the green light to tow with your car will be Dodge as they rated it, engineered it, and will be who would have to honor the warranty of the vehicle. Clearly you have the drivetrain to tow with your Challenger, but the other things to consider is the cooling capacity of the engine and transmission, the brake power, the frame strength, suspension components etc. That said we have a 2 inch hitch that fits...

  • Where Is the Rear Threshold Plate On a 2017 Dodge Challenger When Installing T-One Harness 118656
    The rear threshold plate as Tekonsha calls it or the rear scuff panel as Curt calls it can be found in the attached photo. I have also attached for you two sets of instructions, one for the Curt T-Connector Vehicle Wiring Harness part # C56230 and one for the Tekonsha T-One Vehicle Wiring Harness part # 118656. These are different harnesses yes but they install in the same place which means the process will be the same. I recommend you take at the instructions for the Curt T-Connector even...

  • Trailer Hitch Availability for a 2016 Dodge Challenger SRT
    Yes, the Curt hitch part # C13093 that you referenced has been confirmed as a fit for your 2016 Dodge Challenger SRT so it would work well for you. It does fit a few Chrysler vehicles though so I can understand the confusion. I attached an install video that shows it getting installed on a similar 2013 Challenger. For trailer wiring you would want the part # 118656. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts;...

  • Difference Between Tekonsha T-One and Curt T-Connector Wiring Harness for 2019 Dodge Challenger
    Both the Tekonsha T-One # 118656 and the Curt T-Connector # C56230 are custom 4-Way trailer wiring harnesses that will install the in the same exact manner on your 2019 Dodge Challenger (by plugging into factory ports behind the tail lights inside the trunk and running a hot lead to the battery). The primary difference between the 2 kits is simply in the brand name but the Tekonsha T-One # 118656 does have a higher amp capacity than the Curt, which is why I recommend going with the T-One...

  • What Does Curt Trailer Hitch C13236 Look Like Installed on a 2017 Dodge Challenger
    I have included a picture showing what Curt trailer hitch # C13236 looks like installed on a 2017 Dodge Charger. I think that the hitch and its positioning match the lines of the vehicle quite well which is not normally the case with trailer hitches. But this one blends nicely. If you plan on doing some towing I recommend Curt Ball Mount for 2" Hitches - 1" Rise, 2-1/4" Drop - 7-5/8" Long - 7,500 lbs Item # C45030. It will accept a hitch ball with a 1 inch diameter shank such as # 63845...

  • What is the Height of the Draw-Tite # 76145 on a 2016 Dodge Challenger for Choosing a Ball Mount
    When we installed the Draw-Tite Max-Frame Trailer Hitch Receiver # 76145 on a 2018 Dodge Challenger we found that from the ground to the top of the inside of the receiver measured 9-1/4" as you can see in the attached photo. It might be a little different for your 2016 Challenger but this should give you a ballpark idea of what you need. You will also need the T-One # 118656 wiring and a ball mount to tow. I have also attached an installation video for you to reference as well as a link...

  • Towing Capacity of 2016 Dodge Challenger and Hitch Recommendation

If you have an automatic transmission I have added the chart for trailer towing weights for your reference from the owner's manual. If you need a hitch, I recommend Curt Trailer Hitch Receiver part # C13093 which is a custom fit hitch that also has a concealed cross tube for a nice clean OEM look on the Challenger.

  • Class III Trailer Hitch with Best Ground Clearance for a 2016 Dodge Challenger
    The picture of Curt trailer hitch # C13236 is correct but that is just one design that is available for the 2016 Dodge Challenger. Hitch # C13093 has the square tube with the receiver below the cross tube. The round tube design though, # C13236, would have slightly better ground clearance than the square tube design. The receiver will basically be right beneath the bottom of the rear fascia. Please note # C13236 does not fit models that have quad-tip exhaust. If you plan on doing some...
