Hopkins Custom Fit Vehicle Wiring - HM40155

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into OEM tow package wiring harness - no cutting or splicing required.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing
    • Locate connection point behind rear bumper
    • Plug in connector
  • 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 factory tow package wiring harness, which is located behind the rear bumper, near the center of your vehicle.


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.

This plugged right into the truck wiring harness and was ready to go. As I understand it, there are two types of plug ins into your factory harness. Mine was more round rectangular rather than just round. Make sure you order the right one. It plugs right in behind the bumper on the driver's side of the spare tire. It was easy and worked great. 469150

  • Recommended Trailer Tow Harness For 2014 Honda Pilot
  • We have a solution to your question. However, this particular tow harness, part # HM40155, fits 1999-2001 Ford Super Duty Trucks and does not fit your 2014 Honda Pilot. I recommend the Curt Wiring Harness, part # C56170, as the best fit for your needs. The Curt harness is built with surface-mount technology (SMT) that makes it smaller than "traditional" circuit boards. SMT eliminates the need for leads and performs well under rough road conditions and/or excessive vibration. Several...

  • 7-Way Trailer Wiring Kit for 2015 Honda Pilot

This kit includes the 7-way socket, harness, converter box, and relays. Please refer to the linked review video for more information on this kit.

  • Trailer Wiring Harness Needed for a 2005 Honda Element
  • I do have a solution that will work for your 2005 Honda Element but unfortunately neither the Hopkins # 43105 or their # HM40155 are confirmed fits for your vehicle. Instead you will need to use a universal option like the Tekonsha Wiring Harness Kit # 119147KIT. This comes with quick splice connectors that allow you to tap into the light functions on your Element. It also includes the wiring needed to run to your battery so that your trailer lights aren't pulling from your vehicle...

  • Available OEM Trailer Wiring Harness Kits for 1999 Ford F-250
  • Hopkins Plug-In Simple Wiring Harness # HM40155 has a 4-pole flat trailer connector and is intended as a replacement for a factory 4-pole on your 1999 Ford F-250. We do have other wiring kits for your truck depending on how it was equipped from the factory; all kits are shown on the linked page. For example, parts # 118243 and # C55243 are 7-way kits that include fuses and relays to activate the additional circuits for the trailer.
