Does the 2025 Subaru Outback Wagon Onyx XT Come with Trailer Wiring

Question:
I bought a new 2025 Outback Onyx XT. Do you know if this model has a trailer wiring harness. Other Subarus Ive owned did but I cant find one on this Outback. Thanks

Hey Chris, thanks for reaching out!
The 2025 Subaru Outback Wagon Onyx XT does not come with trailer wiring, according to the chat feature on the Subaru website (so take that for what it's worth).
Because of this, I recommend picking up the T-One Vehicle Wiring Harness # 118467 because of how reliable the Tekonsha wiring is. Please note this installs on the passenger side of the vehicle.
Attached is an installation video of this wiring kit on a 2024 Outback Wagon.

Hey Chris, how did things go with the T-One wiring harness on your Outback? Did it connect smoothly on the passenger side like in the video? Your update could make it easier for others adding trailer wiring to their Outback.
