Wiring to tachometer/odometer

The odometer screen on our Hunter 41DS has become blank. I'm going to add a standard Hobbs Meter but I need to determine what the wiring is to the connector in the back of the Siemens tachometer/odometer. Does anyone know what source might have the wiring diagram?

Just connect it to the oil pressure switch.

I apologize for being dumb, but where is the oil pressure switch? On the engine? There is an oil pressure gauge on the same panel next to the tachometer/hour meter though.

I am sorry but I do not have a service manual for your motor. The oil pressure sensor looks like a round 1 inch by 2 inch barrel with wires coming out of it on the motor. Once the pressure is up the connection closes. So you may be able to tap into the oil pressure Gage, but you would need to test the voltage to make sure that it is correct, and not just integrated with the instrument set. The low pressure light, is likely energized backwards of what you would need( normally closed).

look around the oil filter area on your engine they are usually close by
