Omori EGT

[stevepudney]

I've just bought a set of used Omori gauges from Japan one of which is an electrical EGT gauge. The problem is I have no wiring diagram. for the EGT gauge.

Yes, I can drill a hole and tap a thread in runner No 4 on the exhaust manifold to fit the probe but were do the wires from the probe and the back of the gauge actually go. See the photo below

All I know is the white and the black from the gauge make the light work. So if the white from the gauge is lights and the black ground where does the white from the probe connect to???????

Could anybody shed any light on this

YHPM, but here is my best guess from looking at the picture,

Orange - Red on Sender
White - White on sender
Black - Earth
Red - +12v
Yellow - Light
