Everyone here knows it is a pain to d/c the ground cable in the trunk bc of the spare tire lying on top of the battery.

Let's say one just wants to prevent a battery drain and do not have a charger (sometimes ppl park at airport for wks) etc...

Does anyone here know the fuse(s) that feed whatever item (such as ECU etc. that creates parasitic drain) that one can simply remove to prevent current drain? Then once you return (let's say at the airport etc), simply reinsert the fuse(s) and drive away?

Thanks!
