Check out Anderson Powerpole Connectors on google, amazon, etc. I and many
others use them for remote trickle charging and battery maintenance, jump
starting both ways, and running 12 stuff external to the car. Some mount on
the pedestal as you say, my diesel mounts under the rear bumper and goes
directly to the ground and starter hot pole. Buy yourself a pair of jumper
cables, cut off one end and mount a power pole connector to that end (they
are hermaphroditic, there is nothing special about which part you use on
either the car or the cables) and you will never have to open your rear
hatch again to power or get power from the battery.
