DIY - 2009 Cruise Control for $10, without pulling the steering wheel and airbag

[ditso]

I really enjoyed CTScott's instructions on how to add cruise control. I haven't purchased a Yaris yet but I'm planning to do so this spring. Since CTScott obviously is a very smart individual, I was wondering whether he could provide instructions on how to add a headphone jack in approximately the same location as the two cruise control switches. The jack would not necessarily need to shut off the speakers in the car--just tap into the sound system. Before someone goes ballistic on how "unsafe" this is, I would like to point out that my drive is very early in the morning on an interstate with very little traffic. I would take the headphones off when driving in serious traffic. Thanks.
