    Whats the correct way to wire a Kill Switch? There's one green wire and one black wire coming out of the back of the switch. Is the black and ground? This Phucker came without any diagram or instructions, can anyone help???? Thanks in advance.

    unless the switch was designed for a magneto-type ignition, you can simply use the two wires to interrrupt the positive ignition wire going to the ignition box. doesn't matter which wire goes where, just cut the igntion wire in half and wire each end to a wire on the kill switch. when the cap is on the switch the wires are connected internally and when the cap is pulled off the circuit is cut.

    If it's a Merc round switch with black and green wires its a mag switch which is normally open with the cap on and completes the ground circuit, grounding the mag with the cap off.
    The Merc switch with the 2 white wires is for bat ign and is normally closed with the cap on and breaks the ign circuit when the cap comes off.
