[Newbie wiring AtomX / G4X into a SandRail w/ a stock NA EJ22 Subaru]

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.

1. 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 ?
2. Same question for the  Water Temp Sensor, MAP Sensor, Intake Air Temp Sensor, and Throttle Pos Sensor.
3. Same question for the  ground wire coming from my Coil Pack / Ignitor.
4. Same question for the  ground wires from my Injectors.

If you see any other "lunacy" in my diagram, please speak up.
