E70 hitch/ harness install / programming question

[Kormaster]

Hi guys

I got the tow module programmed. How do you verify if it worked? I dont have access to my trailer right now so I bought a 7 pin connector tester



All the lights work and left/right/reverse/brake works.

BUT - brake controller light and PDC/Camera function doesnt work. PDC still goes off when connected and no fancy reverse camera function.

Maybe programming didnt work? Maybe I screwed up on the install?

Im using Prodigy RF controller. Since the oem harness has brake controller 4 pin and that is not hooked up to anything, is that part of the problem? RF module only hooks up to 7 pin and communcates with RF handheld so no wire to run inside the car. If brake controller pin is not active, maybe i screwed up tapping the 3rd pin from the tail light harness and that is the wire communicates with AHM module
