Usually right behind the distributor. in the back of the block.
Screwed into the engine block under the distributor.
The oil pressure sending unit on a 1989 GMC Sierra is located slightly above the oil filter. You will need a flashlight to find it. It may be hard to recognize it because it should have a heat shield around it as well. Look for its wire coming down from the engine compartment and follow it to the oil pressure sending unit. Drain your engine oil and remove the oil filter to make changing the oil pressure sending unit easier.
