Hopkins Custom Fit Vehicle Wiring - HM11143885

  • 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 - 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
    • Locate connection point in rear cargo area
    • Plug in connector - no cutting or splicing
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • 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


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 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. You will have to remove the cargo area cover and interior trays to access this harness. Once you've plugged in the connector, insert the provided fuse into the in-line fuse holder.


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.

This wiring kit lasted only part of a season. I don’t blame etrailer, they only sell the part. Just go to [retailer] and buy their kit. It’s cheaper and better built.


Comments
Thank you so much for your feedback on the harness. I am sorry to hear that it did not last for you. The harness does have a limited one year warranty. For your 2018 Subaru Outback Wagon I recommend part # C56040
Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
$31.06
which has the highest amp capacity of the harness that fit.

2022 Subaru Ascent

Easy install “plug and play”. The wiring past the junction box is a bit short but it works and makes it far enough to the hitch opening for the 2022 Subaru Ascent




by:

The unit worked correctly, and was not to difficult to install. The only issue we had was the connector was in a different spot that indicated. But was easy to find it once we realized the issue.

Shipped quicly, and works. So we are happy




by:

Wiring in the 2022 is in different location than previous models. Etrailer needs to update their videos. The plug is under the rear panel by the liftgate latch. Literally takes popping off cover and plugging it in.




by:

Outstanding service , follow up and great installation video




by:

The instructions were not accurate for a Crosstrek, they might be right for an Outback. When I called Hopkins for support, they werent very helpful. They ended up telling me to call a dealer. I reached out to etrailer support and Joshua was fantastic. He asked me to send him pictures and he found other instructions that helped me complete the install. This harness also wont fit through any body holes, so they basically have you running it out the hatch and closing the hatch on the cable. Not ideal and not hidden, but I guess it works.


Comments
I would agree that the Hopkins instructions are vague for the 2016 Subaru CrossTrek. Each of the trailer wiring harnesses that fit your 2016 Subaru Crosstrek will be stored inside the rear hatch compartment. It can be completely out of the way though, as you can lift up the panel in the rear hatch where the connector is and simply store the connector there. Harnesses are specifically designed this way for many vehicles that are not considered full-time towing vehicles as a way to help protect it from damage. If you want to have the harness stored outside your Subaru you will need to drill a hole to route the harness underneath. The best method would be to pull up the carpet in the rear of the vehicle, looking for an existing hole or knockout. If there is a knockout, remove the center piece and run the wire through. If you cannot find an existing hole, you will have to drill one. Any time you run electrical wiring through the car body, you will want to use a grommet to prevent the wire from rubbing against the opening and eventually shorting out. You will also want to use silicone sealant to seal up the hole around the wire to prevent exhaust from entering the passenger compartment.

2017 Subaru Outback Wagon

Extremely satisfied with the customer service that I received to determine the proper equipment for my application.
I am looking forward to the OEM plug & play installation of my wiring harness for my Subaru Outback.




by:

Plug and play worked great.




by:
2022 Subaru Outback Wagon

Great plug and play. Would have liked trailer pigtail to be a few inches longer.




by:

Thanks to etrailer's incredibly helpful video and excellent products, my Subaru is styling with a new hitch and electrical. I'm not much of a do-it-yourself kinda guy when it comes to vehicles and this was actually a pretty fun project with no drilling, cutting or other invasive procedures that I probably would not have enjoyed. Buy the right one and just go for it!




by:
2022 Subaru Crosstrek

Works great have used it several times latest install on a 2022 Subaru Crosstrek




by:
2016 Subaru Outback Wagon

This installation could not be any easier, took me less than half an hour, the video was right on and it went together perfectly. I like the fact that the plug remains in trunk when not in use and is not exposed to the weather. I would strongly recommend this product.




by:

Installation went great. Do not overthink it, easy as can be with a perfect fit.




by:

Easy to install. Works well

Less than 30 minutes to install this item. Very easy for any user with basic mechanical skills. Installed on 2022 Subaru Outback.

Very easy to follow video, installed it in 30 minutes.




by:
2010 Subaru Outback Wagon

Installed this in my Subaru Outback. Was very straight forward, and the video on etrailer.com also made it very easy. I rate myself maybe a 7 out of 10 in handiness, so if you're the same way, you can definitely take it on.




by:
2015 Subaru Outback Wagon

The Hopkins wiring harness is great, came on time and packaging was good. This went on my 2015 outback easily and works good. The only thing I did different from the instruction was after plugging into the cars wiring I ran the rest of the wire into the spare tire area and cut a slot in the rubber plug in the bottom and continued the connector along under the car to the trailer hitch then mounted the plug to the hitch with a bracket I made out of small angle iron bolted to the hitch. Then sealed the rubber plug around the wire with rubber cement and made sure all the slack in the wire underneath was gone so as not to catch on anything while driving. I did it this way because I didn't want to run the wire out the rear hatch door when connecting it to the trailer And it looks and works good.




by:

Works great.




by:

Fits perfect super easy install




by:

We have no issues with the functioning of the trailer lights.




by:

Great product. easy to install.




by:

Installed hitch and separate wiring harness in about 3 hours. Videos were very helpful for both, especially for wiring. I wouldn’t have been able to find the wire connection otherwise. Like some of the other reviewers i managed to keep the middle tab in the bumper and cut around it. Like the hitch so far. Thanks etrailer.

  • Troubleshooting Backup Sensors of 2017 Subaru Outback Not Functioning After Trailer Wiring Install
    Based on how the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Connector # HM11143885 installs it should not have any affect on the backup sensors. Most likely what happened is the harness of the sensors got disturbed when you installed this kit. I'd recommend going over the install and seeing if you can find where the sensor might have gotten unplugged or damaged.

  • Where is My Connector Plug on My 2022 Subaru Outback Wagon?
    As far as the harness, based on your recent searches, I believe you are referring to the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Connector # HM11143885 for your 2022 Subaru Outback. I confirmed with my research that the plug is located under the rear trim panel on the passenger side, just inside the rear storage compartment on your 2022 Subaru Outback. I went ahead and attached a video that shows where the plug is located using another 4-way wiring harness. The installer...

  • Trailer Wiring Recommendation for 2015 Subaru Outback Wagon
    Sounds like a short damaged the converter box of the harness you have. This happens typically when there was a pretty bad short on the trailer wiring. The boxes are designed to short themselves out when they sense a bad enough short to prevent the short from transferring to the vehicle's wiring. So what you'll want to do is find out where the short is on your trailer and fix that so that when you replace the wiring you don't also damage the new kit. The Tekonsha kit part # 118467 is the...

  • Best Trailer Hitch Recevier for 2017 Subaru Outback
    I definitely can and the best trailer hitch receiver for your 2017 Subaru Outback (with any engine) is the Draw-Tite Trailer Hitch Receiver # 76227. This is the best hitch because it has a concealed crosstube so your Outback can maintain its from-the-factory appearance, has the best ground and bumper clearances, and has capacities of 600 lbs tongue weight/4,000 lbs towing which is as much or more than the other hitches. I have added a photo showing how this hitch will look once it is...

  • Recommended Trailer Wiring Harness for 2015 Subaru Outback 2.5i
    The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118467 is the one I recommend over the other two for your 2015 Subaru Outback 2.5i. This brand of harness has less issues than the others. The Hopkins # HM11143885 and the Curt harness # C56040 are very similar as you stated and all three will work well. It is the same product made by 3 different manufacturers. I personally would get the Tekonsha based on the reputation of reliability and customer feedback.

  • Best Trailer Hitch for 2020 Subaru Outback Wagon
    The best trailer hitch for your 2020 Subaru Outback is the Curt Trailer Hitch Receiver # C67JR because it has by far the best combination of value and utility. It has a better price point than other options while maintaining the highest capacities and a concealed look. Really, this trailer hitch is the best of all worlds for your 2020 Subaru Outback and if it were mine, this is definitely the way I would go.

  • Curt C13410 vs. Draw Tite 76227 Trailer Hitch Receiver for 2015 Subaru Outback
    There is very little difference in bumper clearances between the Draw-Tite Trailer Hitch Receiver # 76227 and Curt Trailer Hitch Receiver # C13410 that fit your 2015 Subaru Outback. You aren't going to hit a knee on either, as the face of the hitch on both is about equal to the bumper. The biggest difference we saw between these two hitches when we test fit them on a '15 Outback was that the Curt hitch offered about an inch more ground clearance than the Draw-Tite, but otherwise the hitches...

    It sounds like you're needing to install the Load Resistor Kit # DI34ZR so the Hopkins Wiring Kit # HM11143885 on your 2016 Subaru Outback Wagon is able to read the trailer lighting system properly. What these basically do is pull a little more power for the trailer lights which makes it easier for the vehicle to recognize the trailer is connected. I recommend installing the resistors closer to the trailer connector rather than the lights so you don't have to get a resistor for each individual...

The Curt and Draw-Tite are both cost-effective and they have towing capacities of 600 lb tongue weight and 4,000 lb towing capacities.

If it doesn't have brakes then the Subaru maxes out at 1,000 pounds. Additionally, there's kind of a weird statement that says "When towing a trailer on a long uphill grade continuously for over 5 miles (8 km) with an outside temperature of 104 degrees F (40 degrees C) or above", the towing capacity is 1,350 pounds.
