Need help with Magnus install

[Halon]

Here's a couple pic of my engine bay with the battery lowered. Kinda hard to see but maybe gives you a little better idea or something. I had to remove the Evap crap though. Sit's down in there nice and snug for now. I do need to clamp it down still somehow though. For now it's just placed down in there, and it stays put no problem, and it's worked fine like that for a year. But at the track, that may be another story. So before going to a track I gotta figure a way to clamp it down.
