Another silly question.

I noticed this yesterday. I have two oil pressure gauges, factory and aftermarket. Both sending units are mounted on the oil filter pedestal. At some time, the wiring was redone with some extra long wire that is coiled up underneath the cruise control unit and brake fluid reservoir. Both wires from the sensors just hang down and just rest on the lower part of the engine and actually were resting on the steering linkage (or whatever that is called). I was worried that the movement would eventually cause fatigue or wear on the wires.

So, how should the wires from the oil sensor be routed. What was stock? Any photos?
