I'm trying to run 12V cables straight from the battery to my trunk to power a 410W power converter. It looks like 8 gauge wire will be my safest bet, but I have no idea how to actually get cables routed back there. If there's a 12V line directly connected to the battery that is closer than the engine compartment then I may use that instead. My plan right now is to run it back on the driver side in the cable runs at the bottom of the doors.
