Does anyone know where this "light green" wire that I am supposed to tap into to use the PAC SWI-ALP should be?

The instructions have a sketch of some plug that is at the base of the steering column, and it says to tap into the light green wire. Well at the base of the steering column there are like 8 plugs and none of them look like the sketch. I can also find multiple wires I would consider light green.

Does anyone know which wire it is on an 04 tahoe (with Bose if it matters)? Pics would be awesome.

Here are the instructions and the picture of this plug http://www.pac-audio.com/swixprogram...ehicles&ID=261

thanks,

 

Never mind I found it. You have to take off the metal cover under the steering wheel column in addition to the lower trim panel and it's on the left side of the column.
