You are correct it is just a switch that turns on an idot light on the dash that says no/low oil pressure. I used a egr socket (take the sender to pep boys to find the correct socket) a short 3in 3/8 drive swivel socket wrench and patience. Some have removed the oil filter support to get at it. Since this sensor is not shown in the 90-92 manual most do not know it is there.
