What's this cool switch and green light on my lower dash do?

[Harry]

On my van it starts the on-board compressor.

On my rig that switch is for the Aux backup lights in the rear bumper...

The switch and light might not have anything to do with each other...plus I have 6 switches on that kick panel, air, amps, backup lights, electric steps, high idle, & backup alarm.
Mine (the green light) is the 4x4 engaged indicator but just because it's on doesn't mean it's fully engaged...I've seen that before

I have a 2006 also and have the same set up except it's on the right hand side. The light is my 4wd indicator and the switch is my on-board air compressor switch.

I was thinking it may be the auxiliary idle switch, assuming the van is a diesel.

That's the fuel efficiency switch. The van gets 10 with it off and 25 with it on, which you can then brag about on forums.
