If any of those last 4 positions are momentary switches I doubt the indicator will light up. But I know how to get them to light up if they work in the way I think they do.
I think the indicator light circuit for the monetary switch is like this
Witch would mean the connection pin for the switch has - or + going through it at different times.
The way I think it works is like this.
When you hit the switch it gives the BCM a Negative signal to turn whatever on. Then once the BCM turns on what it powers, the BCM sends a low voltage POSITIVE signal to the switch board using the same pin and then that turns on the indicator light.
To find out for sure I would need to pull out my switch board and test it.
