I acquired a set of GNX style VDO gauges for my 87 GN.
The car is an LS swap car (I got it like that don't jump on me) with electric speed output, and I want the speed to display on the mechanical VDO speedometer. It looks as if the only way to do this is with a $400-500 convertor box.
That said does anyone know how difficult it is to remove the 3.5" mechanical speedometer and wire in a 3.5" GPS or electronic speedometer? What are the white and black terminals circled on the back of the speedometer for? Backlight?
Also has anyone trimmed a factory instrument cluster bezel to fit one of these? Any tips?
