We have had some progress then
The oil pressure switch is normally closed.
When the pressure of oil reaches around 14 psi, it pushes the switch to open the circuit of the bulb by disconnecting it from ground.
A length of wire connected to ground can indicate the point of faulty connection.
With the ignition switch on and the engine off, touch the closer point to the bulb with that wire and have somebody see if the bulb lights up.
If so, keep touching points downstream towards the oil pressure switch.
The problem (open circuit) should be between the points of light and no light.
