Orange & Black = ground. One of those will be the switched side of the switch. In this case, that wire will be grounded, too. With a meter, you could measure resistance to ground and verify. To tell which one is the switch, you need an ohmmeter or continuity checker.
Green. That will be the wire from the BCM.
Lt Blue = illumination. If the light is normally on with the dash lights (I haven't noticed mine), then I think you got that one right, too. It would be nice to be able to check the voltage as the dash lights are adjusted to confirm this.


Grn/Wht & Blk/Yel = ground. See above.
Drk Blue. Same as Lt Blue above.
Blk/Red. Should be coming from the BCM but I haven't look at the schematic so it may be Ign.

A cheap multimeter from the auto parts store (or WalMart, or Radio Shack, or ...) will be good enough for what you are doing and they can be found for $5-20.
