Ah OK. So for the Injectors, the common wire from the Injectors (Yellow Wire) in my Schematic should go to +12V ign Accsy Pwr in my schematic. For the Ignitor, I'll ground to the Engine Block. Thanks Adam !

Some help would be appreciated! Everything is in place now and I'm getting ready to wire up to my Atom-X connector. I think my basic wiring (see diagram) is in order as the majority of it is stock-Subaru from the donor vehicle - but I'm a little concerned with proper grounding of Sensors / Injectors / Coil Pack. Should the low-side of my Crnk and Cam Snsr be wired to Atom-X "Gnd Out pin 24", or to vehicle battery ground at the ECU ? Same question for the Water Temp Sensor, MAP Sensor, Intake Air Temp Sensor, and Throttle Pos Sensor. Same question for the ground wire coming from my Coil Pack / Ignitor. Same question for the ground wires from my Injectors. If you see any other "lunacy" in my diagram, please speak up.
