Save some money - go to radioshack and buy a 1/2 watt 2.2k ohm resistor - they sell them in a pack of 5 for 99 cents.
Crawl under car, pop off CAGs harness, and where you'd normally clip in the skip shift eliminator, you plug the resistor into (bend it like a U and stick each end into the cags harness hole). Wrap it in electrical tape to secure it, and protect from moisture.
I've also heard "skip shift eliminator" plugs have more wires/parts and lower QA on them, and some seem to burn out and make your CEL go on. I've had resistors on all my f-bodies for years, and never had a problem on it - I put it on within the first week of getting the car, and years later, I forget I ever did it!
Oh, and the job on the camaro is pretty much identical to the vette - just on different ends of the car.
