It sounds like you are needing a 7-way connector for your 2021 Subaru Crosstrek to tow a trailer with brakes. You are already on the right track with the T-One Vehicle Wiring Harness # 118467. You will want to install the # 118467 and then adapt that 4-way into a 7-way using the Universal Installation Kit for Trailer Brake Controller # ETBC7 (the only way to get a 7-way is to install a 4-way and adapt it into a 7-way). You can then use the No-Drill Mount Bracket # 18136 to provide an attachment point for the 7-way bracket included in the # ETBC7.

For a brake controller, I recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR. This will provide you with a sleek proportional brake controller knob that doesn't need a bulky controller in your Crosstrek. It will install using the Universal Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers # RED69FR and you can add the Universal Mounting Panel for Redarc Tow-Pro Trailer Brake Controller Control Knob # 331-TPSI-001 to provide for a more factory appearance.

I checked the owners manual of your 2021 Subaru Crosstrek and it is flat towable as-is which you can confirm if you check out the owners manual as well. You'd need to start with the Blue Ox base plate kit part #BX3622 which is a confirmed fit…

If you have a vehicle specific wiring harness for a brake controller then that would indicate that you have a factory tow package and subsequently would already have a 7-way at the back of your vehicle. The universal 7-way connector #ETBC7 is meant…

There are a number of factors involved when converting a semi 7-way to an RV 7-way. Semis generally use a 7-pin round pin socket, similar to #PK11720. And RV style 7-way uses blades, like #PK12706. We do not offer any pre-made adapters to make this…

Answer 11

Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make…
