Yes 1 wire have to be pulled from the comfort module there's located behind the glovebox. It's only needed to pull the signal / +12v wire to the doors from the comfort module since you can take earth from the door somewhere :)
You'll have to locate connector F on the module and then left door (LHD) is pin 5 and right side is pin 12.

However I'm not sure if these should be switched over when you have a RHD car?
