I have a late build '02 2500 4x4 and the switch that operates the indicator light is sleeping with the fishes. This is a non-CAD axle so the switch is a rather simple SPST, screwed into the top of the transfer case. The part number I keep coming up with (5083138AA) doesn't look anything like what's in the truck. I did a search here, but kept coming up with the vacuum switch for the CAD. Anyone have a part # for this ?
