i recently bought a used boat. the ignition switch was broken. i got a universal ignition switch but i don't know what wires go on what terminals . i had the wires marked the same as the original switch but after it was handled so much trying to find the correct switch the markings have worn off. does anyone have a color code or diagram as to where the wires would go on the universal switch. i have tried to trace the wires but there are a few i can't tell where they go please help. thanks
