2010 Dodge Ram Pickup - T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • Custom Fit
  • Trailer Hitch Wiring
  • Tekonsha
  • 4 Flat
  • No Converter

Quickly and easily install a 4-way trailer connector on your Dodge Ram Pickup. This T-One typically plugs directly into the back of your factory-installed 7-way connector so you can retain the 7-way and also pull a trailer that has a 4-pole flat.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Retains functionality of factory-installed 7-way, RV-style connector (if present)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind rear bumper
    • Plug in T-connector
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage: 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 behind the rear bumper. If you have a factory-installed 7-way, blade-style connector, the T-One will plug in between the 7-way and the OEM socket.


Once installation is complete, the 4-way flat 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 4-pole connector itself - to help prevent corrosion.

unable to locate factory wiring to connect this harness to. sent a search party who said it was located inside of a frame member. still searching...there are NO wires showing under the vehicle and i have not started to pull apart the interior in a search as the weather is uncooperative. i do like the fact that the 4 wire in enclosed in a loom for protection. my last vehicle did not have that feature. it is thoughtful. 462005

  • Can 4-Pole Trailer Adapter, # 118384 Be Used at the Same Time as Another Connector, 2010 Dodge Ram
    The 4-Pole Trailer Adapter, # 118384, is a T-style connector. When plugged into a truck that has an existing factory trailer connector, that factory trailer connector will remain functional and you will be able to use either one. However, I advise against using more than one of the connectors at the same time. Doing so can overload the circuits and cause electrical damage. I have included a link to the installation details for this harness for you to view. The harness itself is rated...

  • Brake Controller Fuse Location in 2011 Dodge Ram 1500
    The fuse location for an electric brake controller in a 2011 Ram 1500 is position J02 and it takes a 30-amp fuse. This is shown in the manual on page 564. The part you referenced, T-One 4-Pole Vehicle Wiring Harness # 118384, is a basic wiring harness that carries only lighting signals but not brake power for a trailer. For a 7-way wiring set-up for your 2011 Ram 1500 that includes a trailer brake power circuit you can use kit # 74682. This plugs in to the factory wiring connector. If...

  • Recommended Vehicle Side Pigtail To Use with T-One Vehicle Wiring Harness 118384
    In order to replace the pigtail that plugs into the back of the trailer connector you can use the Tow Ready Replacement 7-Way Harness and Socket for Factory Tow Package part # 20147 which will then work with the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118384.

  • Connecting 3rd Brake Light in Leer Cap to 2019 Ram 1500
    Actually, the correct part to wire in a truck bed cap's third brake light is the converter # PP20-702. Since your 2019 Ram's turn signals and brake lights run on one circuit this separates them so the light on the cap functions with just the brake lights. Each yellow wire connects to the truck's brake light/turn signal circuits, one on each side, and then the green wire goes to the third brake light. You can use the truck's trailer wiring to find the proper brake and turn signal circuits....

    I do have an option for you but the T-One Vehicle Wiring Harness part # 118384 is not a confirmed fit for your 2018 Honda Ridgeline. Instead, you will need to use the T-One Vehicle Wiring Harness part # 118778 which plugs into a pre wired connector under the rear bumper. There is also a converter box that gets installed inside the cab which you can see from the attached install instructions. Unfortunately, there is no adapter that will allow you to use the T-One Vehicle Wiring Harness...

  • Parts Needed to Add a 7-Way Trailer Connector to a 2012 GMC Acadia
    The short answer is that wiring harness # 118384 will not fit a 2012 GMC Acadia if it does not have the factory tow package. The harness is meant to plug in line with a factory 7-Way trailer connector. If your vehicle does not have the factory 7-Way then it will not fit. To add a 7-Way you will first need to add a 4-Way, # 118451. Then you can add a 7-Way by using 4 and 7-Way installation kit # ETBC7. I have included a couple of links that explain the ETBC7 installation. If you also...

  • Where to Find Connector for Installing Brake Controller in 2010 Lexus GX460
    To install a brake controller in a 2010 Lexus GX 460 the correct install harness is the part # 3040-P. This adapter plugs into the 5-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how...

  • No Running Lights on Trailer When Using Tow Ready T-One Harness 118384 on 2004 Chevy Silverado
    Since you have replaced the factory 7-way connector on your 2004 Silverado due to corrosion you may also want to check the condition of the pins on the round vehicle connector under the rear bumper. This is the connector that mated to the original factory 7-way socket and that may now mate to the T-One Harness # 118384 if you are using this part. Since the outside contacts on the 7-way were corroded it is also possible that the other upstream connections may need cleaning as well. Even...

You will connect the brake controller wiring with the vehicle wiring already present under the dash. I've attached a video of this installation on a 2005 Trailblazer for you to check out.

  • Can Curt Easy Mount Bracket be Installed so Connector is on Right of Hitch Receiver
    I don't see any reason why you couldn't mount the Curt Easy Mount Bracket for 4- or 5-Way Flat and 6- or 7-Way Trailer Connectors # C58000 so that the connector is on the right side of the trailer hitch receiver as opposed to your left. It secures with hardware that you'll tighten so it should work just fine with the connector on the right. And it will work with your GM's connector without issue. I have added a link to a video review for you as well of the Curt Easy Mount Bracket for...

  • Adding a 7-Way Trailer Connector to a 2013 Ford F-150 that Came with Factory 4-Way Flat
    Your 2013 Ford F-150 must have come with the factory 4-Way connector. Since the harness for that connector uses a square plug and not the round plug, a simple plug and play 7-Way is not available. You will have to partially hardwire in a 7-Way using # 37185. I have included a link to a video that shows how this is done on a 2013 Ford F-150.

  • Is There a Difference Between 4-Way Adapaters # 118384 and # C55384

  • Correct Trailer Wiring Harness for 2012 Jeep Liberty
    To install the # 118384, you would need to unplug your existing 7-way harness from the rear of the socket. The # 118384 would plug inline between the vehicle harness and the existing 7-way, as shown in the video I linked you to. If your Liberty does NOT have the factory tow package with the 7-way trailer connector, the connector that the # 118384 would connect to will NOT be present. In this case, you would need part # 118554. I have linked you to the installation instructions for the...

  • Trailer Wiring Harness for a 2011 Toyota Tacoma Access Cab
    The definitive way to determine if a vehicle has a factory tow package or any other options is to have a dealer run the VIN number. Although if there is no 7-Way connector at the back of the truck, you most likely do not have a factory tow package. To install trailer wiring, you would need to use the custom fit vehicle wiring, # 118496. I have included links to the installation instructions and a video showing a typical installation. If you then wanted to add a 7-Way trailer connector,...

  • Adding a 7-Way to Bumper and Bed of a 2012 Ram 2500 that Originally Came with a 7-Way
    Usually when there is a question on the function of a wire the solution is to test that wire. But you indicated that you have tested the wires and still cannot figure out the functions. But you didn't say why that is. Were you getting conflicting readings from the meter? A meter might be a little too sensitive for this test. Really all that is needed is a circuit tester such as # 40376. Two of the wires will show power when the brake pedal is pressed. And one of those wires will also...

The connection point is located behind the factory installed 7-way trailer connector, or up by the spare tire of the Jeep Liberty (GM Jeep Liberty only).

If the Jeep does not have the factory towing package you will need to have a Jeep dealer activate it for you. Otherwise the harness will not work.

    What is really frustrating about factory integrated brake controllers is that even the ones that say they are compatible with electric over hydraulic brakes don't always work properly. The factory controller of your 2013 Ram 3500 is supposed to be compatible with EOH brakes but we've found that in a lot of cases the only solution is to bypass the factory controller with an aftermarket one that consistently works with EOH actuators like the Prodigy P3 part # 90195.

A ground issue will show up when there is a load on the circuit and having a constant draw on the circuit like with running lights could be what is making the ground issue appear.

    If the trailer has LED lights then the issue isn't the adapter or the trailer. It is the vehicle. The 2012 Mercedes GL450 and other German vehicles do not work well with trailers that have LED lights. This is because LED lights do not draw enough power for the tow package on the vehicle to recognize them. Usually this is accompanied by a bulb out sensor light in the vehicle.
