Reply to "Gas tank electrical connections"

So, hijacking this to continue the same discussion - this is what I have on my gas (petrol over here) tank.

I have a black on the ground / earth, a white black and a yellow black.

The black is ok - as black through this car at least seems to always be ground. Nice.

This leaves the white black and yellow black.

I found a '74 wiring diagram on another thread in here that suggests the white black is the fuel level wire - which is cool, but the diagram shows the low fuel light as being a solid yellow wire not a yellow black.

In my dash the yellow black is consistently connected to the instrument lighting, so being lazy and not belling out the cable is it possible that they could dual purpose the yellow black in the dash to the instruments?

I'll get the multimeter out and answer my own question sometime today - but thought I'd ask here too.
