I plugged in a transfer case switch now my fuel and temperature gauge don’t work

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Well, I'd say disconnect the switch hand see if everything goes back to normal. If yes, I would suggest checking the circuit that the wiring connector is related to for electrical shorts. I would check for any blown fuses in the related circuit to thhe transfer case as well as the instrumentation and gauges. Why is the transfer case switch disconnected in the first place?
