So im doing a dual battery setup for my boat, i know it is not a car, but it is pretty similar.

My main question is where do i run the "true ignition wire"... So far im thinking i can wire it into the "on" position on the key?

Looks about right. Crude drawing but looks right.

HA yea, it is crude. So any sugguestions on this "true ignition source" where will i find it? Is the the "on" wire behind the key the right place?

Hook ignition to a source that turns on when your stereo turns on like your radio fuse in the fuse block.

Can i hook it up to the remote turn on from the harness with say a 5 - 10 amp fuse?

Should be fine. And as far as I know a fuse isn't necessary
