The CAN bus isn't connected to the OBDII connecor on Brammo cars. The wires exist in the harness, but were cannibalized (at least on the early cars) for the Masterlube solenoid. I think later cars got a dedicated Masterlube wire, but the CAN bus still isn't connected to the OBDII connector, though it may be connected at the ECU end. Note that properly, a CAN bus needs some termination resistors, but it works (at least for me) without them.
