Yup also have mine where lighter used to be..had to widen hole but it looks neat and the best thing i foudn was you could wire the gauge up to the wire(cant remember what colour now) that was in the lighter so when you turn your headlgihts on your gauge lights up =]
although bad side is cant see it for shit unless you look around gearknob when in 3rd gear, was quite annoyed at myself for not thinking about that before i put it there =[
