    Pin outs for the coils

    Greeting all,

    This is my first post so be gentle.

    Does anyone have a schematic diagram of the pin out's of the coils on the LS1 engines? I assume they run off of the 12-volt battery source and are trigger by the ECU. (There is no voltage step up circuit that would feed a higher DC voltage to feed the coils?)
