i have also done this recently to my VX S2 (more than likely same for VT)and basically i got the green/black wire from down on right side of driver seat under the door sill plastics..
cut that wire and extended it up behind the kick panel to the A pillar where the big plug is....then at the plug find the green/orange wire coming from bcm, cut the green/orange wire and join your extended green/black wire to that...then bcm is bypassed and driver door will work fine but no "auto up" feature etc but thats never bothered me...
