I have found plenty of info on how to do this on an '86 or newer van.
However, how do you do it to an '85?
I know I need to run a wire from the aux battery under the carpet to the
fuse panel, likely something at least 12 gauge, then what?

I would ideally like the radio to turn on and off with the key in setup, but
running off the aux battery.

Anyone?
