relay enclosure

What I typically do is find relay harnesses that connect together (like the ones at www.delcity.net). 

You can connect all the relays in a row and then screw them down to the firewall or some other out of the way place.

I don't know of any premade boxes though.

Any Idea how many relays?

I would go to Pick and Pull and see what I could Find.

Those look like the same harnesses that www.delcity.net has, but Delcity has them for $1.50 a piece!
