Just to give you an idea of how good the details are installing this kit into a Jetta 5. The instructions were for a MK4 VW which IMHO wouldn't be as much as an issue because there is a fair amount of free space under the dash beside the steering colum. You can see where is telling you to run a black wire to a fuse on the 15 circuit. You can't get the fuse block C out enough to open it up... and there were no spare master pins on the 15. The instructions looked like declassified documents with the good parts blacked out. Moving on...
