Re: Installing extra "ign" terminals?
I think you'll still need to get this off of the existing IGN circuit since it comes from the key switch. What you could do is use that to power a relay that then supplies power to an additional fuse box wired off the battery. Similar to how some have run their headlights directly off the battery, with the light switch only carrying a small amount of current to close the relay.
That's a pretty neat idea. I don't want to cut or splice any wires (the original wiring is in perfect condition), so a relay would be a good way to tap some extra juice "straight from the source".
Any other ideas?
