The gauge is blue when on, black face when off & come with the defi individual mount
All are pretty much new, I bought them from Indigo-GT 18 months ago but now without boxes, I have fitted the boost sensor and wired up the controller but never actually been used. - I've changed to a ecu controlled digital dash now so don't need them!
