Hey Charles, is there any way that you have found the wrong harness in your 2025 Subaru Outback Wagon for the Curt trailer wiring part # C56040? I attached a link to an install video for this kit on a 2025 Subaru Outback that will walk you through how to find where this installs. Check that out and let me know if what you have is different.

Hey Charles, were you able to figure out if the Curt trailer wiring harness matched the connectors on your 2025 Outback? Knowing what you found could help others running into the same wiring setup.

all 2025 outbacks have a different connection. the instruction sheet indicated connection left side by drivers seat. there is 2 female connectors ,not compatible with my premium. went to uhaul they ordered trailer hookup and it was connected on the right.
