I'm looking to make a "valet" switch of sorts using my fusion brain. basically i want to have a relay hooked into the accessory line on my m2-atx. When powered the relay will keep the line hot so that my computer doesnt turn off even though the key is out of the ignition. Sound like it would work? Does the FB provide enough power to keep acc hot? If there's something i'm not thinking of by all means let me know lol.
