How to get cruise control

[YarisGoFar]

I'm really stoked about buying my first yaris this weekend, hopefully. Literally pulling my hair out trying to find a LB 5 speed with cruise, don't have much hair to spare. I'm in South Jersey and the dealer found a few of them but the closest is literally 400+ miles away.

I need to make sure I fully understand before my purchase because after reading this, I'll forget trying to get one with cruise and do it myself.
I commute nearly 100 mi. round trip everyday to work and can't do it any longer without cruise on my 2002 Neon. Can't wait!

All I need is a 2010 Yaris 5 speed with the PQ power package, which I planned on buying anyway, then purchase a factory cruise stalk for about $80, a Clutch switch for about $30 and a couple of hours work with a careful install and viola, I have Toyota Factory Cruise Control on my 5 speed with all factory bells and switches, no pun intended?

Any documentation or how to install / mount and wire the clutch switch & stalk?
