Tekonsha Custom Fit Vehicle Wiring - 118361

  • Custom Fit
  • Trailer Hitch Wiring
  • Tekonsha
  • 4 Flat
  • 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 - no cutting, splicing or tapping required. Includes tail light converter.


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 - no cutting or splicing of wires
    • Locate connection points in trunk or rear cargo area
    • Plug in T-connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • 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: 4 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 or rear cargo area, behind the tail lights on both the driver's side and passenger's side. You will need to remove the trim panels to access this harness.


Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your rear cargo area


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.


Tail Light Converter

A tail light converter 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. The tail light converter combines 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.

Product was as advertised. Easy installation and still works perfect a year later. The customer service reps were very helpful (not an over seas call center) Even though I had a ground wire issue (easy fix) they were more than ready to follow up with their install specialist. I was able to find my weak ground. They wicked AWSOME! 521807

Perfect! Super easy. Watch the installation video and you're done. If you're handy you wouldn't even need to do that. Took me 30 minutes or so puttering around. I would buy it again. 497066



- 118361
by:

The video tutorial was extremely helpful. Total installation time was minimal. Instead of pulling the wiring harness under the rear hatch, I ran it through the rubber grommet between the cargo area and spare tire so it could be mounted to the hitch itself. etrailer is the go to place for saving money by doing it yourself. Local company quoted me $476 out the door. I did it myself for less than $200. 466039

  • Trailer Lights Not Working with a CURT Trailer Wiring Harness on a 1996 Nissan Pathfinder
    There could be a couple of issues with the trailer wiring on your 1996 Nissan Pathfinder. Since you have determine that the trailer lights work on other vehicles, we will need to look at the vehicle for the problem. My first instinct is that you have a bad ground connection. The CURT wiring harness you are using has a white ground wire with a ring terminal on the end. This ring terminal will need to be attached to a clean, bare metal surface. If there is corrosion or paint where it...

  • No Trailer Stop/Turn Lights With 2003 Nissan Pathfinder
    The next step in troubleshooting your trailer lights is going to be dependent on whether or not you have a factory or aftermarket trailer wiring harness. If you have a factory trailer wiring harness then you would be better off just taking the vehicle into a service center for repairs as the only advice we would have for this is to check the fuses and relays which you said you have already done. The factory trailer wiring harness can also be bypassed with an aftermarket trailer wiring harness,...

  • Troubleshooting Trailer Lights Not Working After Installing Curt Harness on 2017 Chevy Traverse
    If you installed the Curt T-Connector Vehicle Wiring Harness # C56181 on your 2017 Chevy Traverse and none of the trailer lights are working when hooked up then there are a couple of things you will want to take a look at. The first thing I recommend doing is simply making sure the white ground wire coming from the harness is securely attached. This needs to be connected to a clean bare metal surface on the vehicle's frame to ensure a proper ground. If the ground looks good you...

  • Boat Trailer Towed by 2002 Nissan Pathfinder Has no Running Lights
    I am glad you have managed to narrow down the problem by trying the trailer on a different vehicle. You have isolated the vehicle as being the problem. How to proceed from here will depend on whether your trailer connector is factory installed, or OEM. If the trailer connector was factory installed, it sounds like you have a blown fuse. In my research, I could not find a fuse location for you. Take a look at your owners manual, and look at the fuse box diagrams for the location of...

  • Recommended Wiring Harness for 1996 Nissan Pathfinder to Confirm Working Trailer Light Functions
    It sounds like your running lights are pulling too much power to allow the other functions which on some vehicles requires a powered wiring harness, but this is not the case for your vehicle as just a converter is needed. For a simple and confirmed fit wiring solution for you, I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118361. This harness requires no splicing and the converter needed is integrated into the harness. This custom-fit...

  • Wiring Harness Troubleshooting on a 1996 Nissan Pathfinder
    If your 1996 Pathfinder was hard wired without a converter then you could see this problem. You need to check to be sure there is a converter installed inline on the trailer wiring harness on the vehicle. If there is not a converter you will need a new wiring harness and will need to eliminate the harness presently connected. If there is a converter inline with the trailer connector to the vehicle taillights then start with the trailer disconnected and check the wires leading in to the...

  • Troubleshooting a 2004 Nissan Pathfinder that the Trailer Wiring Blinkers/Stop Circuit Isnt Working
    First thing you need to do is determine if the problem is on the trailer wiring or your vehicle wiring. To do that you will need to test the circuits of your 4-way on your 2004 Nissan Pathfinder with a circuit tester like part # PTW2993 to check if the blinker signals are making it to your vehicle 7-way. Check out the video I attached that details how this is done. If its on the vehicle side it sounds like you are missing a couple relays. There is a relay box under the dash on the driver-side...

  • Troubleshooting Curt # 55400 Converter Installed on 2001 Toyota Highlander
    It is possible for a converter to go bad. You can test the converter by using a circuit tester like part # 40376. Begin by testing the pins on the 4-pole as each function is activated. If some of the functions are not working correctly, test the input side of the converter. If you have signals entering but not leaving the converter, the converter is indeed faulty and should be replaced. I have linked you to a video showing how this is done. However, before installing a new converter,...

All plugs and converters needed for the wiring harness to combine your vehicle's separate wiring system are included.

  • Trailer Lights Malfunction After Adding Light Bar to Trailer Connected to 1996 Nissan Pathfinder
    By adding more lights to your wiring system you could be overloading the system and that could be causing your malfunction. I would recommend to check what the amperage draw is on the CURT # 55361 T-Connector wiring harness to make sure you are not overloading your vehicles wiring system. For a 1996 Nissan Pathfinder the wiring harness that we recommend is the Tow Ready T-One Wiring Harness, part # 11836. It is rated for up to 1 stop/turn light per side for 2.1 amps and for tail lights...

  • How To Bypass the Factory Trailer Wiring Harness On a 2003 Nissan Pathfinder
    If you do not wish to take your 2003 Nissan Pathfinder into the dealer to have the factory trailer wiring harness repaired then yes, it will be best to just replace this with an aftermarket trailer wiring harness. I recommend the T-One Vehicle Wiring Harness part # 118361 which is completely plug and play. This aftermarket trailer wiring harness will work just fine alongside the factory trailer wiring harness as they will be on separate circuits and this option will be far more cost effective...

  • Will Curt Trailer Hitch # 13088 Fit Around the Spare Tire on a 2002 Nissan Pathfinder
    I spoke with my contact at Curt about hitch # 13088, and he stated that there are no fit issues with a factory OEM spare tire and the hitch for a 2002 Nissan Pathfinder. I have incldued a link to the installation instructions for you. If you will be doing some towing I recommend the etrailer ball mount kit, # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a carrying bag. For trailer wiring use # 118361. I have included instruction links for the wiring as well.

  • Trailer Wiring Harness Blows Fuses and Turns On Reverse Lights on a 2002 Nissan Pathfinder
    I do not recommend Curt powered trailer wiring harnesses for LED tail lights because some of the battery power bleeds through and can dimly light up LED bulbs. Harness # C55361 should not have that issue since it does not have a direct connection to the vehicle battery. The harness you are using now, # 118361, might not be the problem and it is possible that if the harness is not the problem that when you install a new one the same thing will happen. It almost sounds like there is a...

  • Trailer Wiring Harness Recommendation for 2001 Infiniti QX4
    You'd want to consider what the trailer has most importantly as that will dictate what style of connector would be the best for you. The most common is a 4-way and 7-way which for your 2001 Infiniti QX4 would call for the 4-way part # 118361. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes...

  • Will the Trailer Hitches for a 2002 Nissan Pathfinder Fit Around the Spare Tire
    There are no known fit issues with the Draw-Tite hitch # 36222 and the factory spare tire on the 2002 Nissan Pathfinder. If you have a larger than factory sized spare, there could be fit problems. I have included a link to the installation instructions for the hitch for you. This is a Class II trailer hitch, the only one available for the vehicle, which may be why it looks different. Class II trailer hitches have a lower capacity than Class III hitches, so you will be limited in what...

  • Trailer Hitch Recommendation for a 2001 Nissan Altima
    To determine if your 2001 Nissan Altima can tow your trailer the first thing you need to do is consult the owners manual of your vehicle. There should be a section on towing that will list if there are restrictions on your vehicle and what capacities it would have. The Draw Tite hitch part # 24690 that you referenced would be the correct hitch to get for your vehicle. This hitch as a 2,000 lb total trailer weight and 200 lb tongue weight capacity.

  • Parts Recommended for Towing Hybrid RV with 2000 Nissan Pathfinder.
    First, you will want a trailer hitch for your 2000 Nissan Pathfinder. I recommend the Curt Class III Receiver Hitch # 13088.

The installation instructions are attached for you. In order to have functioning lights on your trailer, you will also need a trailer wiring harness installed on your Pathfinder. I recommend...

    You should not have any problems. Make sure to stay within towing capacity limits of your vehicle and hitch which I do not see being an issue. I imagine you already have a hitch and trailer wiring for towing for your 2002 Nissan Pathfinder. If not, I recommend the Curt Class III Round Tube Hitch, Item # C13156, and the T-One Vehicle Wiring Harness, Item # 118361, which are confirmed fits for your Nissan. I also recommend reviewing the owner's manual for your 2002 Nissan Pathfinder...

    There is no standard for wire colors so the only way to know for sure what the functions are would be to test the wires using a circuit tester such as # 40376. But that is not necessary because there are T-connector wiring harnesses that fit your 2000 Nissan Pathfinder so you will not have to test and splice wires. You can use Tow Ready wiring harness # 118361. I have linked a video showing an example installation for you. While a hardwire harness could work there are none officially...

  • Brake Controller Recommendation for a 2002 Nissan Pathfinder
    For a brake controller for your 2002 Nissan Pathfinder I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. You will need to start with a 4-way (if you do not have one). For that you would want the # 118361. From there...

    To determine if your 1998 Nissan Pathfinder can pull the 2002 Wildwood travel trailer you will need to consult the vehicle owners manual for the towing capacity of your Pathfinder. If the towing capacity of the Pathfinder is higher than the gross trailer weight when loaded and ready to tow then you can tow it.
