Extra fuse panel

[usafboyer041288]

So I just recently bought a radiator with dual electric fans on it and I'm trying to wire them up. I was thinking I have an extra Fuze panel I wanted to put all my accessories on (boost,water temp,oil pressure,wide-angle, and fans) so that I don't have to tie into any of the fuses under the dash. My question is does anyone know how to wire the extra fuse box in so that it turns on and off with the key and doesn't over load on power.http://uploads.tapatalk-cdn.com/20160705/5efc829314ee0130a5b685480a7ff983.jpg

A key on source of power (many to choose from), or you could use battery power with a switch in the ground

I'm sitting here thinking I have a line coming from the fuse box under the hood to the alternator. But in between that wire I have like a brick. It looks like something you'd use to wire in multiple wires for a amp but it works perfectly. Was thinking branching a wire off it to the bolt on the fuse box and then put the designated fuse in for each accessory. Would that work or would the alternator wire put off to much power

A relay.... You use a relay.
1 pin is key on source that trips the relay
1 pin is the 12v+ constant source
1 pin is 12v+ to the fuse block
1 pin is a ground.

That's exactly how I'd wire it, pick a small or unused 12v ign on source and direct 12v constant with a fuse.
Those connected to the fuse box would have to be on with ign or have there own power on and off switch or trigger.
