Location of the 4WD switch?

[Ahlem]

I have a green 4WD indicator eternally on. The wiring diagram shows a switch.
Where is it located? 4WD selector operates correctly, just seems the switch is stuck.

Assuming Add front end, I believe the light comes on when the front disconnect is connected.

Auto trans t-case has one switch, and a second on the ADD assembly on the front axle.
