hi i have been looking into this for a couple of days now and i still can't see any white vacuum pipe running along the back of the bulkhead, which ends up going under the battery tray, so i guessing someone at some point has for what ever reason taken out the white pipe and the black pipe that goes to the cruise control pump, so what i would like to know is where do i start to install new pipe work to get it working again as i don't know where the white pipe would have gone going towards the drivers side of the bulkhead any help/advise would be great. cheers kieron
