Where are you guys mounting your fuse blocks in the engine compartment?
I'm thinking this is the best location, directly on top of the battery. I can secure it with heavy duty double-sided tape or heavy duty Velcro

 

Big mistake putting it on the battery for a few reasons, namely acid corrosion and when time for replacement. Find a blank piece of sheet metal nearby and attach there.

 

I was going to put it on top of the distribution box underneath the hood. But when I was testing the fit I noticed at the bottom of the hood was pushing down on top of the fuse box
