One line will be 'Hot' full time off the harness,
The other line goes to the relay for the choke/manifold heater.
When the oil pressure comes up, the switch lets the power through and activates the relay for the choke and manifold heater.

You will find the relay sticking out of the harness on the fire wall behind the valve cover.
