I'm thinking about buying an equalizer and I was wondering how they are wired into the system? I've never seen one installed before, and I was wondering if they are a b*tch.

 

The way I've done it in the past is to wire the deck to the appropriate wires behind the fuseblock and do a new ground directly to metal where I could. I then used the wires that originally went to the deck to wire up the eq. I bet I took it too far and you could splice them all together but I tend to always go for overkill.
