So, I'm VERY green on what is and isn't acceptable when it comes to wiring, but I REALLY want to reduce the number of wires running into the engine bay.

What I'd like to do is run the power for the Mallory Unilite, Mallory HyFire IVc, MSD Blaster II, Hurst LineLok, and Electric Fan all off 1 ignition line. I'd like to run the power from the ignition to a junction block that I can run individual lines off of if possible.

The Fan itself uses a 20a fuse, so I'm just not sure if I can do this. The Dizzy also wants a 12v or less power source which is currently running off a goey resistance wire.

My guess is to run a single fused ( 30a? ) line up front, which goes into a fuse block that I can install separate rated fuses in for the different components. Is wire size based on the amperage you plan to run through it? What ga wires should I use? Where should I run my main power source from?

Any and all help is appreciated!
