The PDM is under the Left side of the dash above the parking brake area.



  1. Remove the panel under the dash steering wheel area.
  2. Disconnect the electrical connections for both modules.
  3. Make the electrical connectors as instructed below but do not plug it back into the PDM, but plug the Theft Deterrent module back in.

Leave SW2 (10 switches) the way it is. Close the PRO Module's cover.
