I am a newbie to nitrous and I am in the process of hooking up my nitrous system. I have all sorts of ign on inputs for power I need to hook up. Microedge +, wideband 02, DB gauge, cutout, and so on.

Pretty much all of these wires are really small so they can't be pulling that much power. For the wideband it says to use a fuse no smaller than 5 amps.

Can I come off the fuse box with a larger wire, then a fuse and hook all of my ign power wires to it? OR should I split the wires up and use several different fuses?

This, so far, is my biggest problem.

Any help would be greatly appreciated.

What I usually do is find a fuse under or on the side of your dash that has power with the key on only.
One that you are not using, ie. fogs, 4wd(though im sure your not talking about a truck) etc., thats rated with at least 10 amps. Cut the wire after the fuse and run a new wire to your Key-On accessories.
You may need to pull the fuse and turn the key on to see which wire has power.
