Oil Pressure Sensor warning light

[jbinsure]

So in the middle of my fusible link dilema and the SI board that seems to be going out, I get this warning. This was after I had disconnected the battery to redo the conduit around the fusible link. After I reconnected the battery and started the car, the warning Oil pressure sensor light came on. Could this be triggered by the SI board going out? In checking the Haynes manual, there is no mention of this sensor anywhere. My car seems to have become possessed all of sudden.

Any suggestions/ ideas?

THanks,
Jeff
