Vr Aftermarket Gauge Problems and Interior Lights out

[a.j]

Hey guys,

i was just wondering if someone could help me.

I have just bourght a '94 VR s-pac and someone before me has put in a Oil Press and Water Temp gauge, the problem is, the oil pressure moves around with things like, the bass line in the song, the wipers, the thermo, and the headlights,

does anyone know what would cause this?

im thinking bad earth point, idk, i could be wrong.

and the other thing is,

does anyone know what type of bulbs go behind the heater controls?

cause i dont really feel like pulling it apart before i get the new bulbs.

Thanks heaps

have a look in the how to section regarding bulbs and their replacement
The complete VR/VS interior illumination replacement & conversion guide

re the other problem they could be using the same earth point for multiple things
