Recommended Posts

Any one install a 6 pole battery/engine kill switch? If so what circuit and or wire did you interrupt to shut the engine?

If this is a track car use the GT3 Cup Car switches.

Street and track. I already purchased a switch and wasn't aware of the Cup Car switches. You would happen to know the part numbers?

In any event, I did some testing last night and found that if you disconnect the ground wire from the Oxygen Sensor Injection Ignition relay(located in the Relay Support 2) it shuts the engine down. I just have to snake a wire into the luggage compartment.

There are specific racing rules as to the operation of this switch. Some things need to deenergised and some need to left in working order. Like the safety systems, fire extinguisher systems etc. If you use the cup car switch and wire it as OEM, you will be OK.

As said above, you shouldnt just kill the engine - you need to wire up the relay-like device on the underside of the kill switch (assuming its an FIA style one) so that when the engine is killed, the alternator dumps its charge through a ballast resistor down to ground. If you won't so this, you'll very quickly see the diode-pack in your alternator go "pop", as the alternator continues to make a few revolutions after you've flicked the switch and before the engine comes to a halt. If you've broken the charge path back to the battery (ie the main feed, the one that bolts to the FIA switch), the alternator has no load for those few moments.

As Loren says, in your position I'd use the pukka Cup Car kill switches and wire accordingly. Otherwise I'd google for FIA Cut Out switch wiring for a generic kill-switch.
