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.

  • 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)

    • 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.

Easy installation on 2015 Chrysler 300.

2016 Chrysler 300C

I have a 2016, 300c awd. The Tekonsha trailer wiring harness was easy to install and use. I wasn't to wild about how they colored the power and ground wire. The ground wire is white and the power wire is black (closer to house AC wiring). I would prefer it to be black and red (like automotive wiring). The power wire also asks you to splice an additional black wire on the end of it than a yellow wire on the end of that. Seems like useless extra steps and splicing. Overall, the product made the job simple and easy and I didn't have to cut any factory wires. I would buy it again if needed.

The single passenger side wire is too short to allow much room to find the best place to locate the control module. Other than that, installation was easy and it works well.

great service ANd great product.

Excellent product with excellent design and instructions for installation!



by:

Easy install. Written instructions tell to drill a hole in trunk pan for chassis ground, instead just stack the ring terminal with the main chassis ground on the stud near the battery. Works well overall

Easy to install, customer for life

  • Recommended Trailer Hitch Receiver for 2018 Chrysler 300C
    For your 2018 Chrysler 300C, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 76145. This is a 2 inch receiver that is rated for up to 675 lbs tongue weight. I've attached a video of this installation to assist. The plastic underbody panel will be permanently removed with this installation. If you will be towing with this trailer hitch, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118658. This harness will connect to your factory wiring...

  • Compatible Trailer Hitch Receiver For A 2019 Chrysler 300 Limited
    Yes, the Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 76145 is a confirmed fit for your 2019 Chrysler 300 Limited. This hitch has an easy, bolt-on installation with no welding required. The complete hardware kit and installation instructions come included. I've also attached an installation video to walk you through this process step by step. If your Chrysler 300 doesn't already have a 4-pole connector then I recommend the T-One Vehicle Wiring Harness with...

  • Hitch Mounted Bike Rack Carrier And Receiver For a 2019 Chrysler 300S E-Bike Weighing 70LBS
    For your 2019 Chrysler 300S you will need to check your specific vehicle to determine if your drivers side muffler can be removed. I was unable to find a direct answer from Chrysler as to if this was model year or trim specific. The Curt Trailer Hitch Receiver # C13093 does recommend removing the drivers side muffler to install it but like the other receivers if you have a welded on muffler you can remove the rear fascia to install the receiver. We have added a new feature to our website...

  • Will a 230 lb Bike and a 30lb Carrier Wear Shocks Down on a 2016 Chrysler 300S
    Whenever you will be adding extra weight from a trailer or hitch mounted accessory it is always important to refer to your owner's manual to ensure that you are not exceeding the weight capacity. It is also necessary to note that your weight capacity will either be limited by your vehicle or the trailer hitch, whichever has the lower rating. I looked up the owner's manual online for your 2016 Chrysler 300S and it states on page 457 that you have a max Tongue Weight (TW) rating of 100 lbs....

  • Is Drilling Required To Install a Trailer Hitch On a 2019 Chrysler 300
    The trailer hitch options for a 2019 Chrysler 300 don't require drilling, they install via pre-drilled holes in the frame. I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76145 which has the larger class III, 2" receiver tube opening which is more versatile than the class II, 1-1/4" opening in regards to towing, bike racks, and cargo carriers. In regards to trailer wiring, the T-One Vehicle Wiring Harness part # 118658 is what you seek as it's a direct fit or plug-in-play....

  • Class III 2 Inch Curt Trailer Hitch Receiver to Fit a 2016 Chrysler 300C
    We actually have two Class III, 2 inch trailer hitch receivers from Curt that fit the 2016 Chrysler 300C. Curt # C13236 and # C13093 will work for you. I've linked a video of the # C13093 installed on a 2012 300C for you. If you're going to be towing a trailer with the 300C you'll need a wiring harness for the trailer's lights. The Tekonsha # 118658 is confirmed to fit. It plugs in behind both tail lights then has the hot wire ran to the battery. You'll also need a ball mount and...
