Just about to fit turbo boost gauge and would like to ask what wires connect to.
What colour goes to what on ignition ? As you can see I am novice.
Thanks john

The positive connection on your boost gauge would go to VW ignition (black), the negative would go to VW earth (brown). Backlighting to VW terminal 58b, (blue/grey).

A good idea is to give us a link to the gauge kit you've got.

Did you buy some more tubing,as 1.84meters? not long enough!
As a temporary mesure fit it somewhere in the back of the van and get a mate to read it? [foot to the floor going up a steep hill in second gear]
Post the reading please.

So it's a mechanical gauge, wiring is just for light, black to ground and yellow to dash lighting circuit so it dims with the dash lighting, as per syncroandy's post.

I wouldn't worry about boost, with stock fuelling you won't cause any problems.
They will handle 18psi day in day out with no mods.
