4x4 switch
For what it's worth, I had so much trouble with my 91 4x4 light, I finally do withiout it. It seems that the switch that mounts to the top of transfer case would either short out or open up. I replaced it at least 6 times before I got fed up. If it shorts out the light will stay on regardless of 4wd in or out Easy check, next time light stays on, disconnect wire plug connecting at sw to trans case.
