Your ignitor is basically a power transistor unit, the 6G75 coils have transistors build right in the coils so there no need to use the ignitor unit. So wire the coils ecu signal directly from the ecu.Yes, I have the wiring diagram.
The coils have 12v switched power, and the negatives from each coil goes to the ignitor. The haltech ignition outputs also connect to the ignitor. I tested each coil and they are getting power. There is a home and trigger signal going to the haltech.
