I have a short cable from the battery to the cutout switch. Cable runs from there straight to the starter lug, another branches off to the starter relay (4ga or so). Held up fine for 3 years or so, I soldered my terminals onto the cable. Stuck the terminal in a vice, filled it with solder and melted it down with a torch sticking the cable into it while wet. Seems to be fine, no voltage drop issues.
