I don't quite understand what's going on here. ._.

I can't afford to buy something that doesn't work and/or screw up the installation. >.<

It depends on the year and if it is AT or MT, as to whether it is plug and play at the steering wheel, or if extra work is required:

That I understand, for the record I have a '10 LB Power Package, and I see the cruise light indicator on the dash when I shine a flashlight in the general area.

What I don't get is how do you wire the stalk itself? I don't see any connectors to plug the stalk into.

If you look at the 4th thread in the DIY, he shows the stalk installation. The connector that the stalk connects to is the same one that the horn is connected to. With no cruise, there is just one wire on that connector and with cruise there are three. The OEM cruse control switch wire replaces the existing one.

I'm guessing the cruise switch directs a certain level of feedback down the wire?

Well, either way, after my next payment, I'll save the paycheck after that to gather these parts. Can't wait to install it myself~!

The ECM has an analog input that looks at the voltage coming from the stalk pin, with respect to ground. The resistors between the switches have different values, so when each is pressed the ECM sees a different voltage on the CC pin.
