Cruise Control - Again!

[dono187]

For reference, I am definitely a noob, and have browsed through some of these threads.
Anyways... That all being said, I have an 08 Yaris, without any options except automatic tranny. Just tried installing the OEM cc on the wheel. The install worked great, and was actually quite easy, except that: the Cruise don't work. All I did was pop out the airbag, pop a hole in the plastic behind the steering wheel, stick in the OEM Toyota CC, and put it all back together. That all worked well, but the cruise doesn't kick in. Am wondering if there's something in the ECU I have to do to make it recognize the cc? I did check, and I do not have the cruise light on the dash, because as I mentioned, mine is the very bare bines one.

Thoughts?

FYI, I paid $110, for the OEM toyota cruise stalk and the wirnign harness from Metro Toyota ( cleveland, I think) If anyone is looking for the same, would be happy to post the link to their site. They were very good, and helped me out with the couple questions I had.

Anyways, any advice anyone can spot would be appreciated. Thanks.
