I just made me a sweet new open cone intact (thanks Nawarkk for the how to write up) and because I'm a cheap bastard I don't want to cut up the airbox for the pcm tray like he mentioned. Right now the pcm is just hanging out on the metal shelf and I've heard that people just zip tie it down and call it a day. Two questions though:

1. What exactly am I tying it to? The shelf itself using a big ass ziptie?

2. What would happen if I just left it sitting on the shelf with no zip or other tie down? It doesn't really look like it has any place to go.
