its easy , you cant just break into a VACC line tho , you need to tap into the main boost pipe , as close to the inlet as possible , youll need one of these

drill a hole slightly smaller than this ( or whatever you get) and use the adaptor itself to tap the hole , dont use too much torque as the plastic pipe will shread ( are cupras metal piped??- need a proper tap) this one is from demon tweeks , tho i got one with my defi's , this allows you to then run a VAC tube to your gauge or indeed the wee controller if you have an electronic gauge , ( grommet on passenger side above airbox ( seal the hole) then all you need is a positive, earth and a feed from the dimming switch
