Mine is wired with the optional boost switch to enable starting from
the aux battery. The momentary push-button type switch and indicator
LED are mounted next to a battery meter which shows whether the
alternator has correct output and if either battery is depleted.
Jumper cables are no longer part of my Vanagon inventory.

Large gauge wires (#4 or #6, don't recall) run from both batteries to
the 1315 which resides in the cabinet under sink where my aux power
distribution/fuse panel is also located. Small gauge wires run from
the 1315 to the switch, LED and battery meter which is mounted to a
little panel I made that is bolted to the area below the stereo.

The system has been performing flawlessly since installation and I no
long have to think about switching batteries. It's totally automatic.
