I have been reading over in the Explorer forums for some time now, about how some Explorer owners have been able to successfully upgrade their oil pressure "gauge" into an actual gauge.
Explorers, like Mustangs, have a oil pressure "gauge" on their dash that will indicate only two possible values; "zero" or "normal". That is because Ford is using only a oil pressure _switch_ instead of a true oil pressure sensor. The oil pressure switch is either on or off. To keep the needle on the pressure "gauge" on the dash from being at either one extreme or the other, there is a resistor which is used to roughly place the needle somewhere in the normal range.
The upgrade or fix the Explorer people do, is to replace the oil pressure switch with a oil pressure sensor, Ford P/N E4ZZ-9278-A, and short out the resistor.
Has anyone tried this on a late model Mustang???
PS: This works on Thunderbird Super Coupes too, see
