Help please
I was down in the footwell cleaning the pedals when I noticed a gauge stuck at the back of the centre console ( Only got the car on Saturday )...I pulled it out and it turned out to be a Defi boost gauge!...I had a bit more of a root about and found a Defi control unit ( covered in dust ) with some cables attached to it...I cleaned it up and did a temporary mount with some double sided tape....Question is...What do I do with it????...The gauge lights up when I turn the lights on and very nice it looks too but the needle doesn`t move...also I`ve pressed the buttons on the control unit but nowt happens....I am flummoxed and could do with a bit of advice
Thanks
