ok on the ignition harness there are 3 yellow wires, 2 grey / YELLOW wires, 1 RED / black, 1 BLACK/ green, and 2 light GREEN/ purple wires, and one WHITE/ pink but thats the starter wire!!! the diagram says for accessory 1 = gray / YELLOW and RED / black, and for accessory 2 = BLACK/ light green.... so my question is, do i need to hook up those 2 wires for accessory 1 and the BLACK/ green for accessory 2?? and if i have to hook up both for accessory one... which one of the 2 gray / YELLOW wires do i use or do both need to be used???
