I decided to give this a try and it worked very well. I invested an hour of my time, $19.76 in the cruise control switch #96433106, used some speaker wire and loom I had laying around, one tywrap, a GM pigtail from a 2005 GMC pickup as it had the connectors I needed to connect to the switch, and electrical tape to get the job done. First, I routed the loom/wire from the connection under the dash, over the top of the steering column (under the dash) and up through the tunnel to the shifter. At that point, I cut a small slit in the shifter column material and routed the two wires through it to connect to the switch. I used two connectors that I stripped out of the GMC pigtail and attached them to the wire whereupon I attached the connectors to the cruise control switch. (The connectors are also available at your auto parts store as they're standard GM connectors...take the switch to them and they'll match up the correct size and sell them to you for about a buck each.) I tywrapped the switch to the shifter so it's right there by my right hand. It works very, very well!

Keep in mind that the cruise control light in the instrument display will not work unless you connect one of the two inner posts on the switch and run a third wire to the white connector. I didn't mess with this as I don't need a light to tell me when the cruise is activated.

I'll post 1,2,3,4,5 type instructions when I get a little more time. The big thing is to either solder the connections at the connector or connect the wiring using the same method recommended by most remote start companies - if you can't solder, strip back about 1/2" of insulation off the target wire and split the individual stands of wires in half. Feed the new wire that you'll route to the cruise control switch in between the strands and twist the new wire around the main wire pulling the strands back together. Then secure with some quality electrical tape.
