Bought this from Ebay

I wanted to fit it but didnt want to cut the dash

As I use the BMW clock thingy for storge I decided to fit it in the rear of this
Measure twice, two cuts in the back and crefully trim around the sides to make a hole

Try it for size file it out to suit.

If you look carefully in the picture you can see an on and off switch, the meter is wired to the live for the clock so would be on all the time, so it can be turned off with this switch
Heres the switch, just measuyre this before you buy as it looks to be the same one, its the same supplier
Any questions just ask
