This is probably the dumbest question ever, but I have not really seen the AC controller connections in person, so here goes:

I like how it appears that the 05+ AC controller has a spin wheel for temperature rather than the up/down click button of the 03/04 AC controller, plus it looks better overall.

Is it possible to hook up the 05+ AC controller to my '03 G when I convert to a DD setup or would that just be epic fail?

 

The boards and buttons are different.
