Has anyone fitted an oil pressure and volt gauge from a cavalier to a corsa b. 
I am unsure of what wire does what. I have got 4 wires Black, Brown, Grey/Black and Blue/Yellow.  
I thought it was as follows 
Blue/Yellow- oil pressure 
Black- ignition live 
Brown- earth 
Grey/Black ? 
Is that correct 
 
Can anyone help.

These are easy to wire in 
 
Black - Ignition 
Brown - Earth 
Grey/black stripe - Dash clock illumination 
Blue/yellow stripe - Oil pressure sender or earth out to prevent damage to gauge 
 
I think that's what you need..?

Yeah pretty much. 
 
It's set up as a parallel circuit it will read the voltage across the live and earth then a voltage regulator inside the gauge will give you a reading

I got them off here months ago and they had been modified to fit straight in the stereo slot. Theres a few on ebay but they seem to be getting expensive.
