Hopkins Custom Fit Vehicle Wiring - HM43375

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • Hopkins

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter 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
    • Tow harness with 4-way connector plugs into connection point behind rear bumper
    • Power harness connects in engine compartment
  • Includes a tail light converter 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
  • Protective connection terminals resist corrosion
  • Comes with dust cap for 4-way flat connector, cable ties, and terminal grease packet for electrical connections
  • 90-Day limited warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind your rear bumper on the driver's side. Once you've plugged in the tow harness, locate your vehicle's battery harness plug behind the driver's-side headlight assembly and plug in the power harness with the fuse holder. Run the harness to your battery and connect it to the positive terminal. Then insert the included fuse into the in-line fuse holder.


Once installation is complete, the 4-way 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.


Powered Tail Light Converter

A tail light converter is built into this T-connector. This converter is a battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


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 the trailer. This 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.

Great product

This replaced my 2007 NAPA wiring harness an works perfectly. It was also $35 less than I paid NAPA 11 yrs ago for the same part. Hope this one lasts as long.

Still perfect!

See what our Experts say about this Hopkins Custom Fit Vehicle Wiring

  • 4-Way Trailer Wiring Harness for a 2002 Toyota Tundra
    Wiring harness # 18246 is not a confirmed fit for your 2002 Toyota Tundra but we do have wiring harnesses that will work. To add a 4-Way you can use # C55378, # 118378, or # HM43375. If it were me I would go with # 118378 because it is the best value and we hear about fewer problems with the Tekonsha brand. I have linked a video showing an example installation for you.
