Could you share details on exactly how you re-routed the kick sensor wires? I installed an ecohitch receiver (no cutting of the sensor wires) and yet have lost the kick sensing. I know the OEM receiver requires cutting the bumper right where the wires are located but not so with the ecohitch.I also took my time installing the hitch and rerouted the kicker sensor wires so that it would still work... And it still does. Don't believe the dealer that the kick sensor has to go if you install the oem hitch.
Amp Power, please see this discussion I started and my experience with photos:
