Looking at trying to set up a low oil pressure light on the race car and have sort of an idea, but as usual no hard facts to follow through with.
I am thinking that there must be a " pressure switch " which is attached to a mechanical line off the side of the block.
you would need an extender and then a T junction - one line goes to the gauge and the other line links directly to a " switch " which intern runs to a light ?
Can anyone shed some light on how this might work and also parts needed.
thanks
