Hopkins Custom Fit Vehicle Wiring - HM43354

  • 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
    • Locate connection points behind tail lights
    • Plug in connector - no cutting or splicing
    • Run hot lead to car battery
  • 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 the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the connector, run the red hot lead up to your car battery. Connect the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


T-One Connection Location Points Behind Tail Lights

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.

After a year I am still 100 satisfied. Each time I hook my trailor lights up they work without any issues. Ive used other products on previously owned vehicles which needed constant attention due to poor connections, etc. Your system is simple to hook up and works flawlessly. Great product!

  • Will the Hopkins Trailer Wiring Harness for a 2016 Toyota Tacoma Fit Models Without Tow Package
    The Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # HM43354 is a confirmed fit for a 2016 Toyota Tacoma without tow package. It plugs in behind the tail lights which would be isolated from any tow package wiring.

  • How To Run 12v Battery Wire for Hopkins HM43354 on 2020 Toyota Tacoma
    The best way to run the wire for the 12v power supply from the Hopkins Plug-In Simple # HM43354 to the battery on your 2020 Toyota Tacoma is going to be under the vehicle, while keeping it away from moving parts and parts that could heat up. I've linked one of our helpful articles on routing the 12v power wire to the battery that I recommend having a look at.

  • Why Does 4-Way Wiring Harness Have Hot Lead on 2017 Toyota Tacoma
    Each of the 4-way wiring harnesses for your 2017 Toyota Tacoma do require a hot lead run to the battery, and the reason for this is to power the module. This is needed in your Tacoma and other vehicles in order to protect the tail light circuits from being overloaded, as they are not able to provide enough power without being damaged. You are correct that there are plenty of other vehicles that this isn't needed, though through testing, the harness manufacturers have determined the hot...

  • 7-Way Trailer Connector for 2019 Toyota Tacoma
    If you want a fully functioning 7-way on your 2019 Toyota Tacoma you can use part # 22117. This includes everything you need including the wiring to install a brake controller which you don't need since your trailer doesn't have brakes. If you would prefer to just have a 7-way that powers the trailer's lights and nothing more then instead I recommend installing a 4-way connector, part # HM43354, and then converting it to a 7-way using an adapter, part # 37185. The adapter has the additional...

  • Adding 7-Way and 4-Way to 2017 Toyota Tacoma Without Tow Package
    The reason the 7-Pole and 4-Pole Trailer Connector Sockets # HM40975-11998 has more wires than the 4-pin is because this part is used for a 7-way and 4-way. We can help accomplish your goal but first you would first need to add 4-way # HM43354. From there you will need # 5506, which is similar to the # ETBC7, to get the functions of the 7-way and you can then hardwire # HM40975-11998 to get the look you want. There is no video for how to accomplish specifically what you want to do, so...

  • Installing 4-Pole/7-Way Trailer Connector on 2020 Toyota Tacoma
    We don't offer a 7-way trailer connector that would plug into the connector you mention, but we do have an option that would provide you with a 7-way and a connector for a brake controller. I'd recommend the Tekonsha # 22117 which would plug inline at the connection between the vehicle's taillight wiring harnesses and the taillight assemblies. As outlined in the linked installation instructions, you'll run the body harness to the front to connect at the battery power and ground, with a...
