Oil Pressure Switch

[Anonymous-0]

Where is the oil pressure switch on a Ford 4600 diesel? I just got it and the oil light is on but there is plenty of oil and it runs good, so I think (hope) this might be it.

Directly below the oil filter. Keep in mind that a bare wire leading to the sender will also cause the light to stay on. The sender is normally closed when there is no pressure and it should open the contacts when pressure rises. This sender simply provides a ground path for the light.

Rod,

Should be right behind the PS pump, actually, at least from the factory.
