Question:
Hello, I have been told by my dealer that, if I dont use the factory trailer wiring harness for my 2026 Subaru outback Touring, that it will mess up the electronics in the vehicle. The plug in the car does not match the aftermarket harness plugs. I guess that the harness would have to be hard wired? I hesitate to pay $650 to have this done...especially since I have the skills and am well qualified to do the job myself. Thanks

Hey Michael congrats on the new Outback. To add a custom fit 4-way wiring harness to your 2026 Subaru Outback you will need the Curt item # C34FR72FT. You don't need to use a universal wiring harness that requires splicing.
The Curt item # C34FR72FT wiring harness will add a 4-way connector to your Outback that will allow you to control a trailer or accessories lighting functions. It'll plug into a factory port located by the spare tire in your rear cargo area.
If you also need a hitch, I recommend our etrailer item # e25TR. This is a class III hitch with a 2" receiver that installs behind your Outback's rear bumper. I like it over the Curt item # C67JR because the matte finish blends in better beneath the rear trim.
What do you plan on towing or are you adding lights to an accessory like a bike rack? Feel free to answer this and throw in any other questions you have, where it says Add Comment.
