Gauges work but are limited or data features are limited (turn signals, very
limited gauge functionality).
Ensure 2 pin black connector is plugged into the 2 pin black of the 28 pin

If still experiencing limited functionality, try connecting the black 2 pin from
the TO2 to the OBD2 2 pin black connector, then reset the RR.
