2nd Gen Non-Engine/Transmission 4x4 light switch

[KKunz]

I tried doing a search but turned up nothing. On my 99 there is a switch on the CAD that turns on the 4x4 light when the vacuum motor is engaged. Where is the switch on the trucks without the CAD? Is it on top of the transfer case?

The switch is on the transfer case. It replaces the vacuum switch that you would find on your truck.
