2006 Saturn Vue Redline 3.5L

I've installed an aftermarket stereo, and everything works except for the steering wheel controls. All I need is to know which wires go to the steering wheel radio controls, and I can hook them up accordingly to the unit. There's a Key1, Key2, and Ground cable on the stereo, so I just need to figure out which wires are supposed to connect to those. Thanks.

 

Charm.il has three different radio schematics for 2006 VUE radios. The redundant controls are listed.
