More specifically,

 

That would be it. It seems that the currently available manual is updated. I was just out in my car earlier messing with connections and checked my dip switch settings. For iPod and AUX stereo input use (which are the two cables that come standard with the kit) I have both switches 1 and 2 in the on position, 3 and 4 in the off position. I believe the manual I received in my kit did not have the last portion shown.
