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.

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.by: Glenn05/14/2022
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.

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: Ben10/20/2021
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.

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

Great plug and play. Would have liked trailer pigtail to be a few inches longer.
by: tjs cpa11/04/2020
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!

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.

Very easy to follow video, installed it in 30 minutes.
by: Joe F05/27/2019
Rather than trying to snake your hand up blindly to locate the plug (seen beginning at 2:37 of the 2017 installation video), I STRONGLY recommend removing the the cargo tie-down.
Fold the rear seat down on the driver's side, and gently flip up the carpeted cover (held down with 3 push-pins). With a flat-bladed screwdriver, gently pry the plastic inner piece of the tie-down downward to expose the 10mm bolt. After removing it, and the entire tie-down assembly, you will be able to easily see the plug through the opening. This makes it much simpler to reach in from underneath to pull down the plug.
The rest of the installation can proceed as normal.

Subaru Forester
It took awhile to find out where to plug it in to, the Forester has a different place than the Outback. I did some online research and found a youtube instruction that got me there for where it is in the Outback.

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.

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: Keith 03/15/2021
Easy install. Works as advertised. Plenty of slack to run to your trailer harness. No issues after one year.

by: Mike F10/02/2020
I had trouble for years with previous wiring harnesses I got online, but after doing a little digging and reaching out to the support team I was convinced this new harness was worth a try.
So glad that I found this product to be reliable with no issues. These folks know their product and how it performs. I couldn't be happier.

- Troubleshooting Backup Sensors of 2017 Subaru Outback Not Functioning After Trailer Wiring InstallBased 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.

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...
view full answer... - Trailer Wiring Recommendation for 2015 Subaru Outback WagonSounds 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...
view full answer... - Best Trailer Hitch Recevier for 2017 Subaru OutbackI 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 2.5iThe 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.
view full answer... - Best Trailer Hitch for 2020 Subaru Outback WagonThe 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. If you do plan on towing and need to add a 4-way to power your trailer's lights...
view full answer... - Curt C13410 vs. Draw Tite 76227 Trailer Hitch Receiver for 2015 Subaru OutbackThere 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...

- Troubleshooting Trailer LED Lights Staying on With Vehicle OffIt 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...
view full answer... - Recommended Wiring Harness for 2019 Subaru Outback WagonFor a wiring harness to use with your Curt Trailer Hitch Receiver # C13206 and fits your 2019 Subaru Outback Wagon I recommend the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Connector # HM11143885. This wiring harness uses a T-connector to plug into the connection in your rear cargo area. Once installed you will have a 4-way to power your trailer's signal lights. If you need a ball mount to go with your hitch and wiring, I recommend the etrailer Ball Mount Kit # 989900....

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. Essentially the only real difference between the Curt and Draw-Tite is the fact that the Curt is assembled in the USA while the Draw-Tite is not. Both the Curt...

There isn't a Curt class III hitch for your Crosstrek. For a compatible wiring harness you will want the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Connector item # HM11143885.

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.

- Trailer Hitch, Wiring, And Ball Mount For A 2022 Subaru Outback WagonYes, the Curt Trailer Hitch Receiver # C67JR will fit your 2022 Subaru Outback Wagon. This trailer hitch has a maximum towing capacity of 3,500lbs, and a maximum tongue weight capacity of 350lbs, however you'll want to consult your owners manual for your vehicle's maximum towing capacity, and ensure you're utilizing the lowest rating between the hitch and vehicle. If you're interested in a complete towing setup, you're also going to need wiring # HM11143885, and a ball mount # C45030.

This will provide you with a secure mount that will not require you to drill holes into your rear fascia.
