Romper room is my style here unfortunately it's the only way I knew how to label stuff in the early days of digital cameras.
In the picture you can see the 6 gauge jumper wire from the hot output of the alternator to the starter post. I actually prefer to direct wire the alt to the house bank but for this installation going to the "C" post of the battery switch, via the starter wire was perfectly fine. By sizing this wire appropriately you can better achieve a non restricted output. From the factory this wire was 12 gauge. Be sure to put a good strain loop so you don't weaken the terminations and allow for enough flex.
