Boost Guage Wiring?

[Dominicg.18]

Hello
I own a 2008 GTi and I've been trying to wire a boost gauge into it.

I have fuse taps and followed the instructions given with the gauge but when its wired in the gauge doesn't shut off!
Ive have tried to match up my fuse box with others on the internet but I cant find any like my own. can someone please explain to me which fuse I should be tapping into! thanks

Find the fuse for the rear wiper or cigarette lighter or something that is only powered on while the car is on.
