Specs:

  • Maximum amperage:

  • 90-Day limited warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area on the driver's side and passenger's side. You will have to remove some interior paneling and floor molding to access this harness.


Once installation is complete, the 4-way connector will be stowed in 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-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 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.

this harness fit seamlessly as a replacement for my oem harness that i had to replaced because the converter failed... i called my local toyota dealer for an oem kit replacement and he quoted me a price that was 6-times as expensive. it was a no brainer as to which one to buy. hopefully this one will last so i can't comment on it's durabilty yet since i just replaced it. 570213

The harness was perfectly measured for my vehicle (2000 4Runner SR5) and installed in less than 30 min. After installation it worked perfectly from the first try. Good feel to the product. Shows it was built by hand for your vehicle. Highly recommended. 475567

My 1997 Toyota 4Runner had a problem with it's factory installed trailer wiring. I have a boat and a small lawn trailer and both where having the same issue so I knew it was within the wiring of my vehicle. I looked around the internet for a plug and play wiring harness to replace it with. The factory unit was a plug and play set-up, so uninstalling the old wiring and installing the new system was a snap.( literally ) I just unplugged the old and plugged in the new wiring and done. Works perfectly. Great job etrailer. 349512

  • Recommended Wiring To Add A 7-Way Trailer Connector To 1997 Toyota 4Runner

    After installing the Hopkins Plug-In Simple Vehicle Wiring Harness # HM43415 that you referenced, which is confirmed to fit your 2000 Toyota 4Runner, there are a couple possible ways to convert it to a 7-Way, depending on what your trailer is equipped with.

  • Correcting Reversed Turn Signal Lights on Hopkins Plug-In Simple Vehicle Wiring Harness HM43415
    It sounds like the wiring on your 2000 4Runner needs to be corrected so that the turn signal lights activate correctly and are consistent with the wiring on your other vehicles. First make sure the tail light connectors are installed on the correct side of the 4Runner.
