To install a 7-Way harness on your 2023 Subaru Ascent, without the towing package, you will need two separate wiring harnesses because they don't make just one that'll do the job.

The first harness you'll need is the Curt T-Connector Vehicle Wiring Harness item # C56040. This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the interior trim panel 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.

Some other parts you will need to tow a trailer with your 2023 Subaru Ascent are listed below:

Trailer Hitch - Curt Trailer Hitch item # C25VR

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
