Can't be done without a big spend mate, the passenger side motors are a different part number, without the position encoders.

You'd need a LHD driver seat harness with the extra wires and the motors, as well as the LHD memory switch.

You may also need an iBus connection to the passenger seat as the position is stored in the ZKE, and possibly GND a pin in the seat switch to ID it as the passenger side.
