Trying to install a simple two wire KS one wire from switch went to ground and the other is a mystery. The other wire ? There is a terminal block that has 8 terminals with 5 being used 1 ground whiteon right side then black going to coil. then green, black, yellow all on left side of block. Those 3 are from wire loom from mag/eng.. So where does my other wire from KS go to and how????? Thanks for helping. It must be simple right?!!!
