Hey guys I have to wire in a kill switch for the racecar and was wondering which wire coming off the back do I connect to the kill switch so that it shuts the car off and not continue running? I think it might be the one that says ignition but don't want to smoke a alternator trying it out. This is on a two pole kill switch. Thanks

 

For one you can use the Black/White wire coming from the 15 amp engine fuse. This wire powers the main relay which powers the ECU, coils, injectors etc.

 

I have no wires in the car at all. Starting from scratch and using a Haltech. I have since discovered that I should just wire that to the same fuse that I am for the ecu power. So pretty much what you said LOL. Thanks
