Okay, this is a simple question - what is the best route to run a 8awg wire to the boot? I heard (but have not seen) that there is a spare grommet next to the battery, but as far as I know the cab has a different bulkhead to the saloon/avant. And once the wire is inside the car, is there enough space in the side sills to tuck a 8awg wire in?
Another related question, is there anything I need to pay attention to when I disconnect the battery? You know, some cars need the key in position 2 otherwise alarm goes mental, some cars need specific buttons pressing otherwise airbag light comes on, some stereo (mine is RNS-E) need factory code, etc...
Car is A4 B6 cab, headunit is RNS-E.
