Got the cruise up and working yesterday - woohoo!
Rosta Universal Cruise Control 250-1223,
I got them from http://cruisecontrolstore.com/
for $249.90 I did have a couple of issues and emailed Rostra and they responded the same day with some answers (very helpful). I did find one wire that was incorrectly label. I think the brake switch they had said use a green/red and mine was a green/yellow but overall it went good. I took a bunch of photos and will be making some revisions to how it's laid out but am happy overall.
Dang thing makes a funny noise when starting or changing speeds
(probably the servo in the black box) but it's sure going to make the long drives nice.
I'll write up a report with photos sometime in the next week or two and put them up for everyone to see, ask, etc.
