Question:
I have a 2023 Subaru Forester Wilderness with the factory-installed tow package, so there is a 4-way plug already there. Id like to install a Red Arc Tow Pro Liberty Brake Controller and a 6 and 4-way wire harness to accommodate the 2 trailers I usually tow. From what I can see on your website, Ill need to buy the Universal Installation Kit for Trailer Brake Controller - 6-Way and 4-Way Flat - 10 Gauge Wires, ETBC6 and the No-Drill Mounting Bracket, 18136. I was wondering if there is a vehicle-specific wiring adaptor for the brake controller or do I need to purchase the brake controller with the universal wiring harness? Thanks for your help!

Hey Stephanie, since your 2023 Subaru Forester does not have any factory brake controller install wiring you would need to go with the parts you mentioned to install the Redarc Tow Pro Liberty part # RED52VR. The part # ETBC6 will convert the 4-way to a 6-way and will allow you to wire in the brake controller and the part # 18136 will give you a place to mount the 6-way as well.
Now I would check to make sure the trailer you plan to tow has a 6-way and not the much more common 7-way. Usually 6-ways are only used on horse trailers or livestock trailers whereas the 7-way is more associated with campers. If you do need a 7-way you'd want the part # ETBC7 instead of the ETBC6.

Thanks Jameson. If I'm looking for a plug-and-play option, since I have the tow package, would 3062-P and 331-TPH-017 work with the Redarc Tow Pro Liberty?
