I am putting a 4.0l OHV from a 1996 Explorer into my 1990 BII. I pulled the ECU and complete wiring harness out of a 1991 Explorer and I intend to use that on the 4.0l along with the upper and lower intakes from the 1991 Explorer. I was assembling the 4.0l block and noticed that the oil pan does not have the hole drilled for the oil level sensor. Did the 1996 4.0l Explorers not have a low oil level sensor? Anyways, I really do not want to drill the hole out for the sensor and I am thinking about not putting it in and either disabling the low oil level circuit or removing the lamp out of the dash. Any recommendations?
