Kill switch wiring
This maybe a simple wiring job, I have a stock thunderbolt igntion system on my 330hp 454. How do I wire the kill switch. The harness for the kill switch has two wires, where do they go. Thanks

Wire them to the purple wire coming from the ignition switch. You can cut the purple wire and hook the ends to the wires on the kill switch. It doesn't matter which purple goes to which wire on the switch. The switch is used to break the contact in the purple wire, which is the wire that powers up the ignition. You can find it in the 10 pin harness running from the dash to the engine compartment. If you cant find it then take it from the key switch and run a new wire to the kill switch and back. Hope this helps, Eddie.

You must have a Merc style switch. One wire will be common. The other wires are for normally open and normally closed. The black should be the common. You want to wire it in the normally closed position. The other way is for outboards that use a ground to kill the ignition. You will have to test it with an ohm meter. I can not recall the exact wiring since it has been a while. Hook your leads from the ohm meter to the switch with the lanyard attached. Look for the two wires that have continuity. Then pull the lanyard off and make sure you lose that continuity. The other way will have continuity when the lanyard is off and lose it when the lanyard is attached. You want to be able to complete the circuit when the lanyard is attached. This will allow power to reach the ignition. I think you will need black and green, but I am not positive.
