Good morning, all . . .

I bought and installed the eco hitch on my 2019 3 standard range. The hitch installation went off flawlessly, but the electronics have been a nightmare. I have a couple of questions:  First, the 2019 appears to be configured for a hitch because there is a removable panel on the bottom fascia to allow the hitch to be installed without cutting, and secondly there appears to be a wire harness that doesn't connect to anything zip tied to the top of the bumper under the fascia. Does anyone know what this is? I'm guessing it is pre-installed wiring for the trailer lights, but it doesn't seem to match any configuration for a trailer attachment (eg the flat 4 ) that I've ever seen. I would love to just buy an adapter for the existing wiring instead of trying to get the eco hitch wiring to work.
Please advise . . .
