Hi and thanks to all who read.

I'm going to be wiring in a secondary fusebox that I'm going to use for things like my choke, radio, amplifiers, new dome lights, etc and I'm wondering where I should wire the positive to, I only want it to have power when I turn the key and was thinking about hooking it to the accessory wire on the old fusebox but I'm worried that there might end up being an issue with that. Just looking for ideas to find a better wiring location.

Here is a picture of the fuse box I'll be mounting in the engine bay somewhere:

Good morning,

You will need to take a feed off the ignition switch to the fuse block. I would use a 10 gauge wire as a feed and install a 40 amp fuse for that line alone.

Okay, I attached a diagram for you of the ignition switch. Either the brown or orange wire should only have power with the key on.
