I need help wiring up a safety kill switch for a 1976 mercury 650. I have the switch but i do not know which wires to hook it to on the back of the key switch. can anybody tell me what to hook it to. Also wiring diagrams or pics would be great. thanks for the help
Look on the maxrules.com web site for a wiring diaghram. I do not know if that motor has ADI or Battery ignition. To wire the kill switch properly, you will need to know that answer.
