I installed a P3 controller to my 2015 last month after feeling that braking was less than adequate with IBC. It was most noticeable at low speed stops. The P3 made a big difference. I bought the controller packaged with the cable for my 2015 on Amazon for $140. IBC plugs into a black module box above accelerator pedal. Unplug that and plug in cable to P3. I had no error messages on screen.
The harness you unplugged, was that the harness from the OE IBC ?

I followed his advice when installing my P3 and have had improved braking performance since.
