I have a Lamco boost gauge with two wires.

Yellow and Black

Which one is the Live feed and Earth??

This is just for illumination, right? Assuming this is a mechanical gauge...

If so, it doesn't matter as bulbs don't really care. Use yellow for illumination and black for wiring.

If it is an electric gauge, RTFM :D or hope someone else knows :)

Yep mechnaical boost gauge. I need to sort the wiring out for the lighting.

So Yellow for Lighting the gauge. Yellow wire connected to the fog switch wiring (Purple colour). On a MY99 will I see the purple wire when the steering column has been taken out?

&

Black for earth/ground to chaisis.

That'll do, yup :)

Cheers :)

You won't find the fog lamp switch wiring under the steering column shroud. It's under the panel in front of your knees i.e. where the switch is.

Dave - i guess i'll have to take the paneling off.

I'll have a go tomorrow after my exam.

D'oh, glad someone was reading! Sorry Vinesh.

Your other option is to pick up illumination from anywhere. I got mine from the ash-tray light.

To drop down the surround, there's two screws at the bottom of the dash and a strange screw thing in the side that's hidden when the door's closed :)
