Hopkins Custom Fit Vehicle Wiring - HM40285

  • 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.

    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points in rear cargo area

    • 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

    • Tail lights: 7.5 amps per circuit
  • 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 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.


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.


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.

  • Wiring Harness Compatibility in Police Interceptor SUV Based on 2017 Ford Explorer
    Wiring harness # 118540 is specified for the standard consumer version of the 2017 Ford Explorer on which your police interceptor is based. But since police vehicles usually have major upgrades installed, including heavy-duty wiring, there could be different connectors that are not compatible. If none of the wiring harness kits shown on the lnked page have the type of connector you do on your vehicle then you might consider Hopkins harness # HM40285 which bypasses any factory wiring by...

  • Trailer Wiring for 2015 Ford Explorer without OEM Trailer Wiring
    That does look like half of the factory wiring usually used to install wiring kits that fit the OEM wiring like the Curt kit part # C56172 which you can see in the install video I attached. If you only have that single harness though you won't be able to use this kit since it needs the matching side. So instead you'd need a kit like the part # HM40285 which installs by plugging inline with the taillight connectors.

  • Trailer Wiring Harness for 2014 Ford Explorer with Only One Connector at Rear of Vehicle
    Since your 2014 Ford Explorer does not have the two connectors present at the rear of the vehicle what you'd need is the Hopkins trailer wiring kit part # HM40285 which installs by plugging inline with the taillight connectors.

  • Trailer Wiring Harness for a 2014 Ford Explorer
    Curt trailer wiring # C56172 is designed to fit a 2014 Ford Explorer that came with the factory tow package. If your Explorer does not have the factory tow package then the connectors for the harness will either not be present or they will not be functional. It sounds like your model does not have the factory tow package so you would need to use Hopkins harness # HM40285. It is also possible that the one connector you see and the one that is capped off are the connectors for the tow package...

  • Trailer Wiring Harness for a 2012 Ford Explorer without Factory Tow Package
    If your 2012 Ford Explorer did not come with the factory tow package then there is no guarantee that the proper connector will be present on the vehicle or, if it is, that it is active. The safe option then is to use a harness that will work with models that do not have the factory tow package such as # HM40285. You could then add a 7-Way and retain the use of the 4-Way by installing # ETBC7. And if a brake controller is needed I recommend the P2 # 90885 because it is easy to set up and...

  • Troubleshooting Trailer Wiring Connection on 2014 Ford Explorer
    Thanks for the photo. We don't have anything that is compatible with the harness you show. I believe you disconnected the harness that should be right next to the trailer wiring harness. Please see attached video at the 1:33 mark. If you don't have that alternative harness then you don't have then you will need to use the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM40285 instead of the # C56306 in the video. If that is the case you will then...

  • Trailer Hitch and Wiring Recommendations for a 2013 Ford Explorer Police Interceptor
    First, we have had reports that Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" Item # 76034 does fit the 2013 Ford Explorer Police Interceptor model. When adding a 4-Way trailer connector, # HM40285, to the Explorer it does require a direct connection to the vehicle battery, so it does have a powered converter. But your Explorer might be factory prewired for a trailer connector. Check under the vehicle for the factory wiring as shown in the video I have linked...

  • How to Install Trailer Wiring Harness on 2015 Ford Explorer Police Interceptor
    I would say that it's entirely possible that since this is a police interceptor model that there just isn't a plug in for a trailer wiring harness on the vehicle anywhere; however I do believe this is unlikely. I would look on the driver's side (assuming that you haven't already). If you absolutely cannot find any type of wiring harness towards the back of the vehicle, then you've potentially got 2 options. The first would be the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole...
