To install a 7-Way harness on your 2022 Subaru Outback you will need two separate wiring harnesses because they don't make just one that'll do the job.

If you already have a 4-way harness ignore this and skip down to the next paragraph. 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 the 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.

Some other parts you will need to tow a trailer with brakes with your 2022 Subaru Outback 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

Answer 12

It sounds like there is corrosion in your 7-way connector. Often when there is an issue like this it is due to power bleeding over from the 3 o'clock pin to the 5 o'clock pin. That would then put the full power to the trailer brakes when you…
