DIY Cruise Control on 07-08 Yaris (step by step)

[drunix]

I just finished a 1000 mile trip with the 2 button cruise control and I liked it so much that I upgraded to a variation on the 4 button version. While on the road I picked up a MOMENTARY-OFF-MOMENTARY toggle switch (at HSC Electronics in California, $1.49). I now have Up=RES/+ and Down=SET/- on the switch, a low profile Microswitch push button for On/Off and a C&K white pushbutton for Cancel.
By using 3 differently shaped controls, I can feel the difference, so I don't need to be able to see them. I had the push buttons in my stash.

The toggle switch is similar to this: http://search.digikey.com/scripts/Dk...name=EG2388-ND

Note also this is a 2010 Yaris automatic, stripped down (no power package), and it had the cruise control wiring in place.
