The connections for the doorlocks are to control the vehicles doorlocks from an aftermarket system (from the rf-kit).
You can still program the module though by either following the method for manual transmissions by jumping 12v to ignition temporarily instead of activating the rmeote starter, OR simply doing the 1 key programming method.
