Factory cruise control wiring diagram?

[SmashBack]

So my 79 had cruise control and I'm doing the LS swap thing. I can't for the life of me find a diagram or description of what these factory cruise control wires are doing.

3 coming down column, looks like one was connected to a switch like the brake switch and that jumpered over to an IGN+ source. Then I think the blue and green pair was run to the old modulator.

No matter how it was wired before, I am wondering what these do. The thing has one button...was there just a set button on these or what?

Yes you press the button when you've accelerated up to speed and it locks in on that speed. If you press and hold it you'll slow down and when its released it'll lock in as a new speed. To turn the cruise off you have to tap the brake pedal. Pretty simple system.
