If your vehicle does not have the B&O option that connector is for the tow hitch. Try an audio specialist, some have custom made looms that patch into the system.
Did you ever figure this out? I'm trying to figure out the same thing for my 2019 Ecosport SE.Hello, I have a 2018 Ford EcoSport model S. I'm wanting to install a sub and amp. I noticed that I have a connector under my rear seat. Is that for connecting an amplifier? If so is there a harness that I can't get to hook to an aftermarket amp? I don't want to cut into the factory harness.
