Question:
Hello. 2015 Subaru Outback: Given that the 4 pin is already installed, is this the correct 7 pin to accommodate the AutowBrake requirements? Would this work on newer models of Subaru Outback? Thanks

Hey Kathy, thanks for reaching out!
The Universal Installation Kit # ETBC7 is exactly what you need to get your 2015 Subaru Outback Wagon 4-Way setup to work with the Autowbrake Electric Brake Controller # 3430001.
You may also pick up the No-Drill Bracket # 18136 to make it easier to mount the ETBC7 to the back of your vehicle.
