Hi guys recently converted a 1.9 105 tdi caddy to a 2.0tdi 140 from a touran, straight forward swap all running now but I can’t figure out the wiring for the vacuum block, overall I’m left with approx 10 wires from the loom that have no home and no boost, wiring diagrams show no help from either the caddy or the touran, I can update the exact wires tomorrow when I’m with the van but a few off the top of my head... violet/green, red/black blue/black, black, black grey and many more, anyone able to point me in the right direction on which wires I need for the boost side, I also have the old 3 port n75 from the 1.9 if it’s easier to convert to that if anyone can give me some sort of pin out to wire that into the 2.0.



I converted a 1.9 sdi 2k caddy about 2 years ago to a 2.0 140 from a golf and all I had for wiring was red/black and black/yellow to deal with so I’m stranded as I can’t relay back to that one (pictures of my first one to show I’m not completely clueless lol)
