To tow a trailer with brakes and install a 7-Way harness on your 2024 Subaru Outback Wagon you will need two separate wiring harnesses because they don't make just one that'll do the job. You will also need a brake controller and a ball mount kit, along with the correct wiring harness and bracket to prevent the connectors from being damaged.

The first harness you'll need is the Curt T-Connector Vehicle Wiring Harness item # C56040. This custom-fit T-connector plugs into your Subaru's wiring harness, which is located in your rear cargo area. This will provide you with a 4-flat connector.

The second harness you will need is the Universal Installation Kit for Trailer Brake Controller item # ETBC7. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your vehicle with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it.

The rest of the parts you will need to tow a trailer with your 2024 Subaru Outback Wagon are listed below:

Trailer Hitch - etrailer Hitch item # e25TR

Wiring Harness Mount - No-Drill Mount Bracket item # 18136

Brake Controller - Redarc Tow-Pro Liberty Brake Controller item # RED24FR and Wiring Adapter item # RED69FR

Ball Mount - Curt Towing Starter Kit for 2" Hitches item # C45534

I have linked several installation videos below to help you get these parts installed. I have also attached a couple of pictures so you can see what the etrailer Hitch item # e25TR looks like once installed.
