I just found, and looked at, a service manual. The Onan I have, and prolly yours too, is air cooled and has no temp sensor or way to shut down engine because of heat. The switch we are putting jumpers on is the oil pressure switch, not an oil level switch. Cutting them and splicing them together on the engine side of the cut is simply bypassing them as though they were not there. The controller does not know they are absent.
You will see these two small white wires near the lower part of the engine (sump). They are connected to a screw in switch that is sticking out the side of the casting.
I cut mine and put spade plugs on them so I can bypass the switch for travel and then plug them in to use the switch for camping. So far - so good.
