I'm adding a small, 6 fuse subpanel to make it easier to add some low draw accessories like gauges, etc. Nothing too big, and the total load well below 60A for the whole thing. My plan was to run 6 or 8 AWG wire to it off my auxiliary battery, but I'd like to have all the fuses in it switched, ie on accessory power. My plan was to just put an 80/60 relay on the line and control that with a switched power source, but I'm not sure if that's the best way, or even a good way, to do it. Is that hokey? Is there a cleaner way?
 
That's the way to do it. Find a signal to control the coil side of the relay that has 12V when the key is in the position you wish either ACC or ON. You'll need to look at your wiring diagram to find a signal, but a lot of time the cigarette lighter power is on the ACC circuit so I'll pick it up there if I'm installing in the dash area.

Thanks! That's exactly what I was planning, then realized I'd never read if that was standard practice or not and wondered if there was a more "direct" way to pull in ACC/IGN. I keep adding small things and biting into the old cig lighter circuits, realizing it makes more sense to just run that circuit one time to a relay feeding a subpanel and drive everything off that directly.
