Zeitronix ZT-2 wiring into ECU help

I have a Zeitronix ZT-2 Wideband, Multi-gauge, and their MAP sensor I would like to wire up. I'd also like to get as much data as I can from the ECU (TPS and RPM) so I will have some extra wires to hook up there

Car is a 2000 RS with JDM 2003 STI EJ207 swap w/ ECU. Should be same as a 2002 WRX since I used that ECU for inspection

I used this for the ECU info

The wiring harness for the ZT-2 goes
PIN# | Function
1 Switched power
2 Wideband Analog output
3 RPM input 0-12v square wave
4 MAP Sensor input
5 Warning Output
6 MAP +5v power
7 Ground
8 Sensor Ground (ECU Reference)
9 Simulated Narrowband 02 Output (for your stock ECU)/Linear Wideband output
10 Throttle Position Sensor
11 Sensor Ground (boost Sensor ground reference)
12 User Input 0-5V

So Im thinking

1) 12+V red wire under dash
2) Not going use
3) C9 at ECU?? not 100%
4) Green wire on boost sensor
5) Warning/Not used
6) Red wire on boost sensor
7) Ground to car
8) I dont know if I really need another ground from ECU? But if I do C17?
9) Not going use
10) B7 at ECU?? not 100%
11) Ground for boost gauge
12) Not used
