Hopkins Custom Fit Vehicle Wiring - HM11143865

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • 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 - 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.

Perfect fit, great instructions,dealer did not have hitch and wiring for my new Subaru Forester, nor would have for weeks they said, so I went with etrailer for less than 300.00 dollars (hitch and wiring) a few weeks later the dealer called, said the hitch was in and they would install it, for a total cost of 740.00, well they are no longer my dealer, there is not enough room here to give etrailer the praise they deserve!!!




by:

It's working quite well, for towing my Karavan landscape trailer with my Subaru Forester. The installer reported that the installation went smoothly.




by:
2018 Subaru Outback Wagon

The plug and play Wiring Harness worked fine except that the product packaging lable is outdated (2014). I suggest that etrailer enclose a note with the product noting that is also fits the 2018 Subaru.




by:

quality part. reasonably priced. fast delivery. easy installation. great installation instructions, and video. great customer support.




by:

Works great. Was available before a trailer hitch was available for installation elsewhere. Arrived quickly.

2019 Subaru Forester

Item was as expected and installed easily using your installation videos




by:

Excellent product. Excellent installation videos




by:

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




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.

Super easy install after watching E-Trailer's install video.

Well made, very easy installation!

Haven't opened box yet. I am having GT Customs install the hitch and wiring harness.




by:

Great product and ridiculously easy to install using the video.

This harness was easy to install, and the video instructions was very helpful.

Same as trailer

Subaru Forester

As with past orders this receiver will be a beautiful addition to my Subaru Forester. Always amazed at the products that I receive from etrailer. Thanks for another quality product and great service




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:

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:
2022 Subaru Forester

Easy to install. Plug and play




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:
2022 Subaru Forester

Great product and half the price if a d ealer




by:

Hooked into the original wire harness with one connector. Placement of the 4 post connector for the trailer has lots of options depending on the amount of cutting/hole drilling you want to do. I did none of that so the connector and wiring is stored under the weathertech protector.




by:

I would definitely buy from etrailer again. The price was good and the delivery very fast as well. A follow-up email about my purchase also arrived.




by:

No issues installing the electrical plug. Directions were correct.


Comments
The plug works great after one year. No issues at all.

See what our Experts say about this Hopkins Custom Fit Vehicle Wiring

  • Does Hopkins Trailer Wiring Harness HM11143865 Fit 2018 Subaru Crosstrek
    For your 2018 Subaru Crosstrek the Hopkins trailer wiring harness part # HM11143865 that you referenced is a confirmed fit and would work well. It's a custom install wiring harness that would not require you to modify your vehicle in any way. Your Crosstrek will have the same port for installing this like what is seen in the install video I attached.

  • Installing 4-Way Trailer Wiring Harness In 2013 WRX Hatchback
    The vehicle body harness you need to plug into is located under the left (driver's side) sidewall. If you can't get easy access to it, I recommend removing the panel to gain easy access and then reinstalling the panel once connected. The connector may not be as loose as you expect, but it is there. I've attached the installation details for you. Unfortunately I don't have a video of the installation to attach for you.

  • When Installing Hopkins Trailer Wiring in 2019 Subaru Crosstrek Does Exhaust Need to be Avoided
    You do want to make sure that the 4-way wiring of the # HM11143865 does not get close to the exhaust as it could potentially melt and damage it if so. This isn't covered in the attached install video as the exhaust is far enough away that our installer didn't feel it was important to make this warning but you'd need to use your best judgment.

  • Plugging Hopkins Trailer Wiring into 2017 Subaru Forester
    You would need to unplug what's in the current port that you found on your 2017 Subaru Forester to plug in the Hopkins part # HM11143865 that you have. I attached an install video for this on a 2017 Forester for you to check out as well.

  • Trailer Hitch and Wiring for a 2019 Subaru Forester
    We do have a hitch for your 2019 Subaru Forester, part # 76271 from Draw-Tite. The hitch is rated to tow up to 3,500 pounds but from my research your Forester is rated up to 1,500 pounds as long as the trailer has brakes. If it doesn't have brakes then you're limited to 1,000 pounds. Always make sure you stay within the limitations of the vehicle. To tow a trailer you also need a wiring harness. I recommend the Hopkins, part # HM11143865, because it's the easiest to insall and has...

  • Recommended Trailer Hitch and Wiring for 2020 Subaru Forester
    We have just what you're looking for. I recommend using the Draw-Tite # 76271 since it would allow you the ability to use a weight distribution hitch if you were to decide to tow a different trailer that required a weight distribution hitch in the future. The Draw-Tite hitch is a stylish, round tube design with a 2" Class III receiver that easily bolts into the existing holes on your Forester's frame, so there won't be any drilling required. For wiring I recommend using the Hopkins Plug-In...

  • 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...

  • Concealed Trailer Hitch Fit For 2010 Subaru Outback For Towing Trailer
    You'll want to ensure your current factory hitch can be removed (it should be bolted on and not welded), and if so, there is a trailer hitch receiver with a concealed crosstube that does fit your 2010 Subaru Outback, which is from Curt. Since you mentioned you'll be towing, you'll also need a 4-flat trailer wiring harness, so I'll go ahead and list out both parts for you: - Curt Trailer Hitch Receiver # C13410 - Hopkins Plug-In Simple Vehicle Wiring Harness # HM11143865 You can mount...

  • 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...

    In order to install a 7-way wiring harness on your 2015 Subaru XV Crosstrek you will first need to install a 4-flat wiring harness. I recommend the Hopkins Plug-In Simple Vehicle Wiring Harness part # HM11143865 as it is a direct fit, plug-and-play option for you vehicle eliminating the need to hardwire.

  • Trailer Hitches for 2018 Subaru Forester
    There are quite a few and it can be rather confusing. For starters I recommend getting a Class III trailer hitch on your 2018 Subaru Forester. A Class III hitch has a higher weight capacity and is the larger 2 inch receiver. 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...

    Thank you for all of the information! Essentially you can use almost any drawbar that has a 1-1/4" shank for your application but Draw-Tite does recommend using the Drawbar # 36051 for the Trailer Hitch Receiver # 36644 on your 2019 Subaru Crosstrek. This has a 5/8" rise/1-1/4" drop and is compatible with hitch balls that have a 3/4" shank like the 1-7/8" # 19256 or the 2" # 19258.

It can be used for hitch mounted accessories like bike racks and cargo carriers or towing.

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.
