Does anyone know of a line that would go high only when the egine is off on any honda vehilce? Sort of like what would ideally power an alarm but the amperage is not important. I know that sounds weird, it's for a custom project.

Also, this site, http://www.hondahookup.com/manuals/ seems to be down, anyone know of a similar resource, wiring diagrams and schematics and what not?

thanks in advance for any assistance
