I need help installing a boost gauge.

[Apearcey]

As the title says, I want to install a boost gauge... but I have no idea where to begin!

I'd like to get an electronic one cause I'm a bit of a geek. But where do I begin?! This is my first turbo car.
Any help at all is greatly appreciated!

Wire up the gauge to the fuse box right hand side of the dash behind the cover and I'd get a fuse tap.

Depending on what colours

Red -- 12V accessory Power
Black -- Ground negative
White -- Engine accessory power
Orange -- Head light switch (12V switch power)
Green -- Boost sensor (connect to green wire from sensor)

Vacuum - you will need a boost tap for this coming off the Pcv valve

just wire it to the headlight switch. take 10 mins to do the wiring. run the vacuum hose behind the battery

I used one of these, they're multi coloured and match the dash well.

All of the vacuum hoses are under the bonnet so all you need to run into the cabin are the wires which provide the info to the gauge itself. Much easier! 

Picture here of it installed (about half way down the page).
