It's a 30 dollar part. The unit should be located near the filter. Unplug/Unscrew the old one and insert new and plug in.
Should be at least 10 at idle. 25 at idle would be better.
If your oil pressure is remaining that high, I suggest having it checked with a manual pressure guage to see if the reading is accurate. It sounds to me as if you might have a bad oil sending unit. After checking it manually you may be pleasantly surprised to find that a new oil pressure sending unit will solve your problem. good luck.

The low pressure connection for your 1993 Jeep Cherokee air conditioning system is located on the top of the air conditioning compressor. There is a low pressure connection and a high pressure connection, both should be labeled.
They should never need changed unless one breaks.
Normal idle oil pressure would be around 30 psi. Minimum pressure should be about 10 psi.
In the up position, it should be 20 ohms. In the down position, resistance should be 220 ohms.

It has a chain with a cam gear and crank gear.
On the 88 Bronco it should be just above the engine oil filter.
