Catch Can Problem (Hissing - Plug???)
I set my AMW catch can up like so but when I turned on the Vette I could hear a hissing sound from under the hood and the Check Engine Light came on. 
I checked the hoses and everything was tight but I felt under the catch can with my hand and I could feel air spraying out of the drain hole.
I didn't get a plug and don't plan on tapping the oil pan for it to drain back to the engine???
I just reset all the codes and turned the tubes back to stock. Vette runs great but now I'm driving around with my pretty catch can not hooked up!

Sounds like the draincock is missing. Maybe check in the box it came in. You do not tap your pan for a return line - you just drain it into a container periodically. That's the purpose of the draincock on the bottom. Don't reconnect until you have the draincock in place. Otherwise, your engine bay will be coated in oil soon.

If your drain plug is missing, you can also go down to any auto parts store and buy a replacement brass drain plug. It is a very common 1/8" NPT (National Pipe Thread) size that's been used for years. Just remember that when you screw the plug in, pipe threads are tapered a bit to be self-tightening and make the seal, so when it gets tight, stop there. A little bit of exposed threads is normal. I would recommend using a bit of Teflon tape on the threads to help the seal too. HTH

If you look at all the pics on their website all the catch cans, have a drain **** on the bottom.
