I have a kt35 controller and was trying to figure out how the headlight lead works. Does it only power a relay? Does it carry enough voltage and amperage to power the headlight itself? I also have the lcd8h screen that goes with it. It has the ability to turn on headlight and or tail light. It has a 2 pin sondors style plug coming outof controller thats not used. Its not for the brake switches as both of those are used as well as the pas plug. Thanx in advance for any help.
