No, I'm not manually controlling the banks. The perko switch that I have has only "on" and "off" not like the 1/2/off I've seen. Since, I do not manually switch from battery 1 or 2 then a 16awg to ignition switch is next move? I can do that!
Correct. So now make sure you wire the ignition switch properly. I was a bit baffled but It's clear now..

Purple should go to accessory, causing the isolator to fail open when you switch there.
