Hi Fred, The RDK unit is below/under the dashboard on the drivers side, above the clutch pedal (or where it would be on autos). You don't have to remove any access panels or the dash to get at it. The part number on the unit is 928 618 150 01 (or 00). Disconnect the battery ground strap before starting the bypass procedure. This is for safety and will also clear any RDK faults while you are doing the bypass. Disconnect the connector from the RDK unit, and then place a jumper from pin 13 to 2 on the connector. Tape up the connector to hold the jumper in place and keep the connector clean. You can also open up the connector and put the jumper inside the connector. Use some plastic wire ties to secure the connector back up under the dash, DO NOT try to plug the connector back in the RDK control unit. The Control unit can also be removed very easily if desired (less weight :-) by removing the 2 phillips heads mounting screws.
