I know nothing about this kit, but as far as getting boost/vacuum from your Maggie, there should be a nipple on the back of the unit with a rubber cap on it. On my G8, it is on the drivers side. Not sure if it is on the same side on the Camaro.
Here is a pic of the nipple on my Maggie....It's the capped off nipple right by the rear pulley.
I used 5/32 vacuum hose from the nipple on the Maggie to the nipple on my Aeroforce Sensor.
Then you need to figure out the electrical side of things. I used an add-a-circuit for my gauges.
