I think this is what I've decided on. Uses mini fuses and micro relays and can support a constant 250A. I'm thinking 2 should work, one under the hood to put fuse protection on the injectors, coils, o2 sensors, MAF, and supercharger bypass solenoid, chiller pump, and still have room left for expansion. I'll piggy back off the Infinity Box ECM power feed to act as a wake up circuit for the relays and have an ignition 1 and 2 relays to send power to the fuses.
Interior wise I can feed everything from it so I don't have to buy another $500 Infinity Box power cell and piggy back off one of the ignition power feeds as a wake up signal to the relays and have live battery fed circuits for radio keep alive and interior lamps.
Not a bad size either, 6"x2.25"x2.7". Wires feed out the back so it will need some kind of stand off base or mounting panel.
