Oil pressure sensor 8v wiring.

[Iain]

Size is for the spare plugs in the block. I think the oe place in the back of the pump is a smaller size. In fact may be the right size?

The 1/8 sender was too small.its going in the pump at the back.

Multimeter test. The light will earth via the wire when there's oil pressure (I.e. 0 continuity between engine and pin when running, 1 when not)

So the oil pressure light will earth via the sender unit when the engine is running and there is oil pressure? How does the light work then, how does the car losing pressure and the sender not earthing anymore activate the light?

I am looking to wire in an electric fuel pump in an early carb car and wanted to use the oil pressure sender in the wiring as a safety measure. Was thinking of earthing the relay via the sender unit.

Will also use an inertia switch.
