Features to Know About

Straightforward Installation, But Plan for Access

The vehicle's wiring harness is often behind a trim panel or under the cargo floor. Some vehicles may require removing interior panels or lifting carpeted sections to reach it, but once accessed, the harness installs easily with quick-splice connectors.

No Cutting or Splicing Needed: Custom-Fit T-Connector

Plugging in a trailer shouldn't mean tearing into your vehicle's wiring. This custom-fit T-connector snaps directly into your factory wiring harness, so you can get your trailer lights up and running without any cutting or splicing. Just plug it in, and you're ready to tow.

Reliable Trailer Lighting for Every Trip: Powers Brake, Turn, and Running Lights

A well-lit trailer is a safe trailer. This 4-way wiring harness keeps your trailer's brake lights, turn signals, and running lights powered and in sync with your vehicle. Whether you're hauling a boat to the lake or a camper to the mountains, your lights stay bright and visible.

Prevents Overloaded Circuits: Powered Converter for Safe Towing

Some vehicles can't handle the extra electrical load of trailer lights. The built-in powered converter draws power directly from your battery, ensuring a steady, protected current to your trailer while keeping your vehicle's circuits from overloading.

Keep Wires in Check: Fully Insulated and Weather-Resistant

Towing means exposing your wiring to dirt, rain, and road grime. This harness features fully insulated wires and a sealed converter, helping to prevent shorts and corrosion. It's built to withstand the elements so you can tow with confidence in any weather.

Everything You Need for a Clean Install: Complete Kit Included

No extra trips to the hardware store - this kit comes with everything you need. With fuses, zip ties, and connectors included, you can complete the installation without hunting down extra parts.

  • Stop/turn lights: 3 amps per circuit

This was a much easier install than all the other wiring harnesses that fit our vehicle. This is the only one I found that came with the matching OEM connector. Just plug it in, ground it with the included self drilling screw, adhere the module in a discrete location, and that’s it.

Glad this was a simple install Jeffrey! Really appreciate the photos. Plug and play is definitely the way to go when available. What are you going to be hauling that requires the wiring?

The wiring harness plugged right in to the factory harness. The installation is neat and tidy, and was completed in about 10 minutes.

  • Recommended Hitch for a 2026 Subaru Outback
    Hey Mike congrats on the new car. The Curt Hitch item # C67JR is the only style of hitch currently planned for the redesigned 2026 Subaru Outback. None of our vendors have announced plans for a new hitch that mounts below the 2026 Outback. We'd have them available for preorder if one was in the works. Those style hitches have really gone away the last few years in favor for the more OEM style that hides as much of the hitch as possible. The Curt Hitch item # C67JR is custom fit for your...

  • Recommended Hitch and Trailer Wiring for a 2026 Subaru Outback
    I would be happy to Steve and congrats on the new car. To add a hitch to your 2026 Subaru Outback, I recommend our etrailer item # e25TR. Our etrailer Hitch item # e25TR is a custom fit 2" hitch that will bolt to your Outback with included hardware. This hitch has a 3,500 lbs towing capacity and a 350 lbs maximum tongue weight so it'll work great for towing a small trailer or hauling an accessory like a bike rack or cargo carrier. If you also need trailer wiring, I recommend the Curt...

  • Aftermarket Tow Package for 2026 Subaru Outback Wilderness
    Hey Don! The Curt Trailer Hitch Receiver # C67JR is a confirmed fit for all models of the 2026 Subaru Outback, including your Wilderness package. This is a great hitch for hauling a cargo carrier or bikes and also for trailer towing. It's rated at 3,500 lbs of towing weight, but you'll want to refer to your owner's manual on what the Outback is actually rated for. As shown in the photos below, this hitch is a installed behind the bumper and it's a very involved installation, so I highly...

  • Recommended Hitch for a 2026 Subaru Forester that Does Not Require Bumper Sensors to Be Recalibrated
    No, you will not Daniel. So long as you did not damage or misalign the sensor housings when you temporarily remove the rear fascia, they will retain their factory settings after installing the Curt Trailer Hitch item # C47HR. I do recommend not starting your Forester until you've reattached the sensors. You may get an error code that has to be reset if you do. Other than that there will be no issues. The Curt Trailer Hitch item # C47HR is confirmed to fit the 2026 Subaru Forester. This...

  • Which Hitch is Better for a 2026 Subaru Forester Premium Hybrid? Curt or EcoHitch?
    I sure can Daniel. The EcoHitch Hitch item # 306-X7391 and the Curt Hitch item # C47HR have identical installation methods. They replace your 2026 Subaru Forester's rear bumper beam so the entire cross tubes for both hitches will be completely concealed. Better clearance does go to the EcoHitch Hitch item # 306-X7391. When we installed it on a 2025 Forester the top of the inside of the receiver sits 15" above the ground. The top of the inside of the Curt Hitch item # C47HR sat an inch...
