Default Pontiac G8 GT

I'm curious on how i'm suppose to wire up my ECU connector for my HFS-3 module which is these instruction in the manual

2. Signal to the grey RJ48 connector:
- Red ................. Ignition switched 12V
- Green ............. Fuel injector (-) pin
- Blue ..................MAP sensor (optional)

attached is what i believe the ECM wiring pinout but each fuel injector has its own return (-) . so are are these internally connected so i can hook it to any injector fuel control wire ?

I do see my MAP sensor Signal wire is Pin 58 so all i do is run that wire into my ecm on that pin???
just trying to figure this all out and cut cost on my installer trying to charge me an arm and a leg to do this.
