The wire coming from the oil pressure switch by the pulleys should be a
brown wire. It comes up and meets with another brown wire from the other
oil switch at a 2 pin connector by the thermostat housing. It is common
for there to be a bad connection inside that 2 pin connector. Open it up
and look closely. The other side of the 2 pin connector should have a
yellow wire and a blue/black wire. The brown wire from the oil switch in
question MUST connect to the yellow wire. Sometimes the connector gets
so damaged that someone cuts it out and splices the wires to each other.
If that has happened then it is vital to make sure that the right wires
got joined.
