Kubota Diesel Engine Wiring Problem

[fisherridge]

I have a non-Kabota TLB with a Kubota D1105 3 cylinder diesel engine.
I am having oil pressure switch wiring problems. The instrumentation is idiot lights.
The oil pressure switch has three terminals.
The wire from one terminal goes to the idiot light.
One terminal has no wires attached.
One termminal connector has three wires.
One wire comes from the temperature sender, one wire goes to a bell housing bolt near the fuel shut off solenoid.
The third wire is my problem.
It runs to the dashboard area, but I don't know if it is for power, ground or what.
Any help will be greatly appreciated.

Called in the big guns.
Problem solved.
Don't ask me what the problem was, because I still don't know. I'm just glad it's fixed.

Glad you got it fixed; light switches still mystify me
