Anyone have a wiring diagram for these keys? Boat is getting swapped from evinrude to merc. Boat harness 896537k24. I don’t want to have to use the key switch. Want use the ranger keypad. The key that came with the he harness is the black one. The grey deuteche connector key is the Ranger emergency backup which has the same connector as the keypad. One has two purple and the other has a purple and yellow/black. Need to know what the yellow/black does. Making an adapter to go from the metripac engine side to the deutche keypad
