R50 Duets oil pressure manifold, sender and switches

Need a little help.

The idiot light for engine oil pressure on the overhead display is continually on. I'm guessing one of the two engine oil pressure switches on the engine oil manifold is shot. Does anyone know which of the two switches goes to the overhead display?

The actual oil pressure gauge works just fine.

I dont know which one off hand... disconnect the wiring one at a time... that should tell you.
Typically the variable senders for gauges are larger in size... the on/off pressure switches for idiot lights are usually smaller...

Keep calm and combine on....
