Request for help: diagramming a relay

[Tamago]

the constant wire at the radio is just that. constant.

you don't need to do this at the battery.

Good point, but that only changes one connection point on the relay. A way for it to cut out when the accessory bus is not in use is still needed.

diode between ACC bus and radio feed.. wait nevermind haha...

why not simply shut off the stereo every time you're done using it? or does it still lose its position if you do this?

I can see myself forgetting to turn it off someday and returning to a dead battery. Hence my desire for it to cycle off when the ACC buss is off.

no, i mean shut it off now, don't change the wiring at all. if it's "off" it should retain the settings thru the constant wire, as opposed to resetting while it's in ON and loses ACC power, right?
