I am planning to run LS2 coils on a no GM car with a negative coil trigger. The LS2 coils have 4 contacts. One for 12V supply, One for Coil gnd, One for trigger ground reference, and the other for 5 volt coil trigger. I am using an EFI controller from AEM which has a ground trigger and these coils need a 5 volt trigger. After doing some testing. I connected the 5volt coil trigger connector to a constant 5volt supply and triggered the ignitor by connecting the trigger ground reference to ground. As long as my ground reference was connected to ground I got a spark, for the entire duration. As soon as I removed the ground reference the spark stopped. So with this being said, is it safe to say that I can connect the trigger to a 5 volt contant and then connect the ground reference to the coil outputs of the EFI Controller?

Here is the pinout of the LS2 coils
