From Outside, Any Ideas how to mod/make hatch open when 12v battery is disconnected.

Saved my battery by disconnecting the 12v battery while away for 10days.

The only complaint is climbing into the back hatch area from the back seat.
I would love to some how power the hatch switch to open it.

Climbing into the hatch from the back seat and bolting the battery positive wire, from inside, back on is a real pain because the hatch is shut.

just wondering.
