Tekonsha Custom Fit Vehicle Wiring - 118516

  • 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. 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 - no cutting or splicing of wires
    • Locate connection point in rear cargo area
    • Plug in connector
  • Includes ModuLite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module 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: 2.1 amps per circuit
    • Tail lights: 5.6 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 driver's-side interior trim panel in your rear cargo area.


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


It is recommended that you use a small amount of grease on all electrical connections - the plug 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. 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. This power module functions as a tail light converter to combine 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.


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.

I received my wiring harness in the mail yesterday, just as you said to expect it to be delivered. I installed it this morning. It took about 30 minutes to install. Anyone with minimal mechanical skills could have done it. The instructions with pictures were adequate. The price for the product was very reasonable and works great. I have to thank my son for referring me to your business and I would recommend you to everyone I know or meet. Thanks. 89212

Ask the Experts about this Tekonsha Custom Fit Vehicle Wiring

  • Trailer Wiring Harness for 2004 Mitsubishi Endeavor
    The connector on the # 118516 T-One connector would indeed plug into the trailer connector plug located in the cargo area, under the carpet next to the drivers side wheel well as shown in the photo. Just to be sure, I contacted our representative at Tow Ready, who assured me that the # 118516 trailer wiring harness is compatible with all models of the 2004 Mitsubishi Endeavor. If you don't yet have a hitch, I'd recommend either the Curt Class III # 13569 or the Draw-Tite # 75163. Both...

  • How to Install Trailer Wiring on a 2004 Mitsubishi Endeavor Pulling a Boat Trailer with a 5-Way
    Yes, the fifth wire on your boat trailer is most likely a reverse lock-out solenoid for the surge brakes so that you can reverse your trailer without the brakes activating. I would recommend you install this T-One Connector Assembly # 118516 on your 2004 Mitsubishi Endeavor (instructions attached) and then cut the 4-way off of the harness and then wire up a Hopkins Endurance 5-Way Flat Trailer Connector # HM47900 by function to the wires that are now exposed from the # 118516 to the...

  • Boat Trailer Lights Not Working when Connected to a 2011 Mitsubishi Endeavor
    The first thing to check is the in line fuse that comes with trailer wiring harness # 118516 for your 2011 Mitsubishi Endeavor. If it is not present or blown that would cause the harness to not work at all. There might also be a factory fuse that is missing or blown. Check the vehicle owners manual for any and all fuses related to the tow package wiring so you can check them. If all the fuses are good and in their proper places then you will need to test the harness to determine if...

  • Where Does the 4-Flat Connector from Wiring Harness # 118516 go on a 2010 Mitsubishi Endeavor
    There may be an access point to fish the 4-flat connector under your vehicle behind the side trim panels on your 2010 Mitsubishi Endeavor, but after you install wiring harness, # 118516, the installation instructions state to store the connector in the trunk area when not in use. When you are ready to tow, you simply feed the connector over the door threshold and shut the rear hatch door. Be sure you keep the wires away from the hinge so the wires do not pinch. There should be a rubber...

  • Where is the Trailer Wiring Connection Point for a 2007 Mitsubishi Endeavor
    The connection point for the Tow Ready Wiring Harness, # 118516, on a 2007 Mitsubishi Endeavor is located under a floor panel adjacent to the spare tire compartment. What you will do is take off the floor hatch above the spare tire. You will then need to temporarily remove all floor coverings, 10 mm storage tray bolts and storage trays, exposing the spare tire compartment. Remove drivers side and center foam cargo trays to locate tow plug housing under drivers side foam tray. I have...

  • Trailer Hitch and Wiring Recommendation for 2007 Mitsubishi Endeavor
    For your 2007 Mitsubishi Endeavor the Curt Class III hitch part # 13113 would be a great option. Then for trailer wiring you'd want the # 118516 which is a confirmed fit and our most reliable option. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop.

  • Wiring Harness and Trailer Hitch Recommendation for a 2004 Mitsubishi Endeavor
    We have a wiring harness available for your vehicle, but the hitch part # 75163 that you referenced does not include a trailer wiring harness. For that you would want the part # 118516.

  • Does Draw Tite Hitch 75519 Have Capacity for 3,200 lb Boat
    The Draw Tite trailer hitch part # 75519 has a 3,500 lb towing capacity so it could easily tow a 3,200 lb boat assuming your vehicle also has at least the same capacity. It does come with install instructions. I attached a link to them down below as well. For trailer wiring you will need to order that separately but you would want the part # 118516 which is a custom fit.

  • Cargo Carrier with Bike Carrying Adapter for 2010 Mitsubishi Endeavor
    If you were to go with the cargo carrier, part # CC-100, an adapter is available that would allow you to carry two bikes. The adapter is part # CC-125 and has only been tested with the # CC-100 cargo carrier, although it would likely work with other carriers with the wire mesh floor. It would attach to the cargo carrier as outlined in the instructions which I will link you to. All necessary assembly hardware and straps for fastening the bikes is included.
