Howdy, This was some time ago and I have looked at the video and wiring again and can tell you that the yellow wire on this set up is 12V on the ignition switch. Not the battery "Always Hot" to the "B" post of the key/ignition - most of the time that wire would be red. The Yellow is hot with key on and goes to the regulator box "IGN" on most aftermarket key switches like this one. The yellow wire here is only 12v with the key on. I would say this is the "regulator switch". It took a fair amount of research to find anything on this and I recall there were several different diagrams and set ups and this thing was hacked as you could tell from the old box with all of the blue crimp connectors. I hope that help you. Bobby
Hello, please explain why this yellow wire is connected to the ignition or do you need to supply 12v to it, is this a regulator switch?
