Hi
I have a replacement air charge temp gauge off Mike Rainbird and need to rewire it in to another car.

It has a solid brown coloured wire and a white/brown wire. Can anyone tell me which is the live one?

I've "misplaced" the instruction sheet and took the wiring out of the other car

I know if you connect them the wrong way round they can do damage so don't wanna do that!

Cheers in advance
