  • Hopkins

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - 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
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing
    • Locate connection point in rear cargo area
    • Plug in connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • 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 in your rear cargo area, either behind the driver's-side trim panel or in the spare tire compartment.


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.


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.

Double check to make to see if your vehicle already has the plug and wire for this harness or not. I took the protective cover off of the inside of my 2014 Subaru Outback trunk near the rear driver side wheal and found a plug and wire already routed to power, and compatible with this very harness. saved me a lot of work.

Easy to install. I had to access the wiring harness by the spare tire, then connect the trailer wiring. No cutting of wires or splicing is necessary. Plug and play.

Still working great after a year. No issues. I installed the harness for my Waverunner trailer.

Easy installation

Wires are shorter than in the picture. You have to drop your exhaust so you can lower hitch to pass wire harness between body and hitch crossbar otherwise wire will be too short. Grommet is WAAAAAY TOOO BIG! So unless you want to grind for an hour and hope you keep the hole round your only option is to cut the wires and drill a hole in the factory grommet. This also solves the problem of needing to drop the hitch. This would have been an easy job if the grommet was the proper size and the wire on the end the grommet is on was 6 inches longer. Luckily I had some stainless self tapping screws to mount it in the spare tire well because it wouldn't go any higher with the short wire

I purchased a hitch and wiring harness for my Subaru. My order was promptly filled and shipped. Everything went together smoothly and the how-to videos are outstanding. Big thumbs up to a great company!



by:
2018 Subaru Forester

Friends: When I installed the trailer hitch I did not cut a section out of the heat shield above the muffler. Instead I drilled 5/8” holes where the bolts go through. The shield is already prepunched where it is to be drilled. I used butyl tape around the bolts to seal them and hold the bolts. For the wiring harness, I simply used Velcro to hold the unit to the inside of the spare tire well rather than tape.

2018 Subaru Crosstrek

The DYI videos
provided by etrailer.com provided a quick and easy how-to. It was literally as easy as watching the video on my computer and going out and installing it in 30 minutes. I also installed Mounting Bracket 4-Pole Flat, Item # 18144 and No-Drill Mount Bracket, Short, Item # 18140 and it looks great.



by:

Great YouTube videos reviewing wiring harness options and how to install them!



by:

Super simple installation and works like a charm.



by:

It felt a little expensive, but after shopping realized it was the best product in price. It arrived in the mail today along with the hitch that I ordered from the trailer. The instructions were crystal clear, and I installed it in 15 minutes on my 2012 Subaru Forrester. I couldn’t believe how easy it was



by:

A perfect fit, includes all the pieces necessary, and has plenty of extra wire. I used double sided tape to stick my box to the inside of the spare tire compartment, everything is plug and play and it’s ready to go.



by:

Easy to install and works great. I would recommend getting the mounting bracket that they offer (Item # HM48595) for the connector to keep it secured and easy to access.



by:
2017 Subaru XV Crosstrek

I used this wire harness along with the knockout plug adaptor part number 47605 on my 2017 crosstrek. It is very easy to use both on my crosstrek to make a clean look.



by:

I HAVE NOT USED THIS REAR WINDSHIELD WIPER YET.



by:

excellent fit and built product for the trailer light connections.



by:
Subaru

Easy solo-installation. Precut holes lined up perfectly and instructions were clear and easy to follow. Product performed with zero issues. My wife was rear-ended recently, the 5” rise hitch took the entirety of the blow. After inspections by Subaru they concluded there was zero damage to the car, frame and hitch receiver. 5” rise was bent and replaced. Not sure if its protocol to replace this despite the mechanic’s assessment but I included this to support the idea that this receiver is sturdy and well designed for use well beyond the capabilities of this car.



by:

Installation was simple once I found the connection point. The plug wasn't as easily accessible as the videos showed. Instead, you need to remove the cargo hitch point to find the short lead behind it. Once you have that, it's simple.



by:

Glad one of the videos mentioned the difficulty of reaching the harness in Subaru Outbacks.



by:

Terrible quality. Had shorted out in less than 1 month. Purchased another through another vendor because etrailer would not offer any discount or stand by the product I purchased from them.



by:

Plug and play just like advertised



by:
2014 Subaru Outback Wagon

This was the easiest hookup ever. Subaru plug pulled relatively easy. Make sure you mount the electrical interface box low enough in the wheel well that it doesn't impede proper placement of the foam insert storage tray. I didn't really need this now but likely will in the future. Costs a little more but install and through wheel well to hitch frame makes it the perfect choice and fit for my 2014 Subaru Outback.

Pretty much the same comment applies a year later. Easy install, all good. Only thing is my 4 pin connector cover snapped off somehow and I need to replace it.

Installed perfect a year ago and no problems since. My 2nd hitch receiver from etrailer and I will be back

Just got my wiring harness yesterday in the mail. My nephew will be installing it for me on Tuesday. The same product exactly that a hitch shop was going to install and sell to me for almost 3x as much.

  • Best Hidden Hitch for a 2022 Subaru Forester
    I have a great hitch for your 2022 Subaru Forester and it has a subtle appearance once installed. All you will see is the 2" x 2" receiver. It is the Curt Trailer Hitch Receiver item # C47HR. This hitch installs behind the rear bumper instead of hanging below like most hitches. I have linked a picture and an installation video below so you can see the final product. If you're going to be towing a trailer you will also need the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat...

  • Best Looking Trailer Hitch for a 2018 Subaru Crosstrek
    The best looking trailer hitch that fits your 2018 Subaru Crosstrek is the EcoHitch, part # 306-X7365. The cross tube is concealed behind the rear bumper and the receiver tube is visible underneath. Additionally, the receiver tube can be removed when you're not using it so nothing is visible at all. With that being said this might be a little fancier than what you're looking for. And by "fancier" I mean expensive. The next best looking option is the Curt, part # C13382. It still has...

    Yes, there is a hidden hitch that has a 2" receiver for your 2015 Subaru Outback Wagon. It is the EcoHitch Hidden Trailer Hitch Receiver item # 306-X7601. In order to tow with this hitch you will also need a wiring harness item # HM11143865 and a ball mount kit item # C45534. I have linked an installation video below of the EcoHitch item # 306-X7601 being installed on a 2019 Outback so you can understand the process.

  • Does the Hopkins Fold-Over Mounting Bracket # HM48595 Fit Trailer Wiring of 2018 Subaru Crosstrek
    The Hopkins Fold-Over Mounting Bracket # HM48595 that you referenced can't work with Curt harnesses like the part # C56040 or the T-One kit part # 118467 as it's a bit too small. You'd have to use the Hopkins wiring harness part # HM11143865 or use the bracket # 18144 with the Curt or Tow Ready.

  • Comparing Curt, T-One, and Hopkins Trailer Wiring Kits for 2018 Subaru Forester
    We have three trailer wiring options for your 2018 Subaru Forester. We have the Curt option # C56040, the T-One option (my favorite) # 118467, and the Hopkins # HM11143865. The reason I favor and recommend the T-One kit part # 118467 is because the converter boxes on the T-One kits have been proven to us as being the most reliable. Trailer wiring shorts will easily damage the converter boxes of these kits which renders them totally inoperable but we have found that the T-One converter...

  • 2013 Subaru WRX Impreza Trailer Wiring Harness Recommendation
    Since your 2013 Impreza is a WRX wagon the trailer wiring you would need is a hardwire kit and not the custom install kit part # HM11143865 that you referenced. The # 119250KIT is the way to go. Instead of hardwiring to taillight circuits it uses sensors that clamp around them instead so you don't have to make any permanent modifications.

  • Should Holes on Side of etrailer Hitch e98839 For 2015 Subaru Forester be Plugged
    You have an excellent eye! Those are actually drain holes on the side of the etrailer Trailer Hitch Receiver # e98839. The reason for the holes - which do not have to be plugged - is that the hitch is dipped in a liquid coating for rust prevention, and the holes allow the inside of the hitch to get that coating as well. The holes then allow the fluid to drain out of the hitch. So you don't have to worry about the holes causing any issues after installation of the etrailer Trailer Hitch...

It's a custom install wiring harness that would not require you to modify your vehicle in any way.

There are more accessory options, like bike racks and cargo carriers, that fit the 2 inch as opposed to the smaller 1-1/4 inch size. Of the Class III hitches for you there are basically two designs; a visible cross tube with the reciever coming directly from it...

    Definitely! The main factors that determine the hitch are hitch receiver opening size (either 1-1/4" or 2"), weight capacity offered, and how the hitch installs on your vehicle. For example, if you are looking for a hitch that is compatible with most accessories and provides you with the most weight capacity, I recommend going with a 2" hitch like the Curt Hitch - 2" # C13409. Not only does this hitch provide you with the most weight capacity we offer for your vehicle (525 maximum tongue...

It will require the Hopkins Plug-In Simple Vehicle Wiring Harness part # HM11143865 and 4 to 7-Way with 4-Way Adapter part # ETBC7L for installation. This is a great setup for towing and is very easy to install and setup comparatively.
