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:
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.
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.
Easy installation
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!
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
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.

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.
Great YouTube videos reviewing wiring harness options and how to install them!
Super simple installation and works like a charm.
This system is easy to install and the grummet makes all the difference.
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.
I HAVE NOT USED THIS REAR WINDSHIELD WIPER YET.
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
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.
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.
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.
excellent fit and built product for the trailer light connections.
Glad one of the videos mentioned the difficulty of reaching the harness in Subaru Outbacks.
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.
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.
Plug and play just like advertised
Installed perfect a year ago and no problems since. My 2nd hitch receiver from etrailer and I will be back
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.
Hard to find the connector on car but works well.
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.

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