  • Tekonsha
  • 4 Flat
  • No Converter

Quickly and easily install a 4-way trailer connector on your Saturn Outlook. 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

Specs:

  • Maximum amperage: 7.5 amps per circuit

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.

I'm a knucklehead. Got the wrong part for my Jeep. Nicole was ridiculous awesome!!! How is it possible that a girl knows what hitch wiring part I need when I ordered the wrong one. I asked her that question and she was embarrassed! This girl needs a big raise. When I got off the phone I said to my wife that is the best customer service ever!! Carvana , who I just bought the car from was horrible and needs to learn a thing or two from etrailer. This is not my first purchase from etrailor which is why I returned. American companies need to learn from them people. 938793

Ask the Experts about this Tekonsha Custom Fit Vehicle Wiring

  • 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....

  • 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.

  • 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 4-Way Trailer Connector for a 2018 Honda Ridgeline
    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...

  • Fuse Location for 12-Volt Accessory Power Feed to Trailer on 2012 Dodge Ram 1500
    This typically occurs because of a blown or missing fuse in location J01 in the TIPM box located near the battery. The fuse is a green 40 amp cartridge type fuse. If the existing fuse is blown, be sure to check the power feed circuit on the trailer, making sure that there aren't any shorts in that wiring run. Also check the trailer connector on the tow vehicle and on the trailer itself. Check the pins and sockets for corrosion, sometimes corrosion can spread to the interior of the plug...

  • 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...

  • 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...

  • 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...

  • 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...

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.

  • 2013 Nissan Xterra 7-Way and Trailer Running Light Solution Fix
    Since the solution for no running lights on your 2013 Nissan Xterra is a missing relay and you also want a 7-way kit your best solution would be the part # C56226. You already have some of the relays but you'll be able to use one of the extra blue relays to fix the running light circuit and you get everything needed to install the 7-way. This relay is traditionally found under the dash to the left of the steering column. There is a socket there to plug in the relay that will activate...

  • 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...

  • 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...

  • 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.

  • 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,...

  • Troubleshooting Factory Brake Controller of 2013 Dodge Ram Not Wanting to Work with EOH Brakes
    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.

  • 7-Way and 4-Way Trailer Wiring Recommendation for a 2015 Jeep Grand Cherokee
    The wiring kit part # 118384 is a 4-way connector that would install in line with a 7-way connector at the rear of a vehicle. With this harness you would end up with both a 4-way and a 7-way. If you have a 7-way at the rear of your 2015 Jeep Grand Cherokee and are looking for a harness that will give you both a 4-way and a 7-way on the same mounting bracket you would need the part # HM40975.

  • No Trailer Brake Lights or Turn Signals on a Trailer Towed by a 2004 Nissan Titan
    The first thing you will need to do is determine if the problem is on the truck or the trailer. Start by disconnecting the trailer and using a circuit tester like # 40376 if needed to test the trailer connector on the vehicle. Have someone sit in the vehicle cab and go through each function while you test the pins on the trailer connector with the circuit tester. You can use our wiring FAQ article as a guide to what the functions should be, see link. If all of the functions are working...
