Does anyone know where the wiring hookup is for a trailer hitch for a 4 prong flat trailer light connector for an 06 Forester

I found it.It's in the rear cargo hatch underneath the foam stuff on the passenger side near the spare tire well

Thank you for returning with the solution! I admit I've never used a trailer with my Forester, so I hadn't even looked for the harness. :D

Good luck towing up in PA!
