I have a '93 loyale with just the gas, tach, speedo, and coolant temp gauges. can I swap in the '89 cluster that also includes the oil pressure and voltage gauges?

Maybe, if the connections at the rear of both instrument clusters match. Your car will have an oil pressure switch for the light though and not a sending unit for the gauge so you may have to swap that also.

 

I can say that an 88 DL with the simple (no tach) dash won't accept an 88 GL full gauge dash without swapping the wiring harness. The connections are totally different. If you are lucky enough to have a pick-n-pull yard near you, just pull one of each and have a look to be sure.
