Wiring question: PCM wiring

[seq4x4]

Hey guys, has anyone got a wiring diagram or photos of the harness with what each wire does into the PCM? Mainly focusing on the engine plugs, the body look ones i dont care about.

Any help would be great thanks.

Got a list here of some of the ECU/PCM connector pins and wiring colours for the VS V6.The pin rows and numbers are cast inside the pink and blue ECU plugs.They are small,but theyre there.

Terminal - A3 - ALDL serial data from ECU/PCM,ABS module,and BCM. Red/black wire.
Terminal - A4 - EFI relay & fuse #10. Pink wire.
Terminal - A6 - fuel pump relay. Green/white wire.
Terminal - A7 - throttle position sensor terminal A. Grey wire.
Terminal - B3 - ALDL ECU/PCM diagnostic enable. White/black wire.
Terminal - B4 - intake air temperature sensor. Brown wire.
Terminal - B5 - coolant temperature sensor. Yellow wire.
Terminal - B6 - Auto trans Temp sensor. Black/yellow wire.
Terminal - B8 - Engine fuse & EFI relay. Red/black wire.
Terminal - B9 - Brake fail lamp. Brown/white wire.
Terminal - B11 - throttle position sensor terminal C. Blue wire.
Terminal - B12 - goes to EFI relay. Red wire.

Terminal - C9 - IAC (Idle Air Control ) valve terminal B. Light Green/black wire.
Terminal - C10 -IAC (Idle Air Control) valve terminal A. Light Green/white wire.
Terminal - C12 - is the left and right knock sensors. White/red wire.
Terminal - D1 - MAF (Mass Air Flow) sensor terminal A. Brown/white wire.
Terminal - D2 - Manual trans speed sensor. Violet/white wire
Terminal - D3 - DFI module terminal F. Black wire.
Terminal - D4 -DFI module terminal C. Light Blue/black wire.
Terminal - D5 - Auto trans speed sensor. Light Brown wire.
Terminal - D9 - DFI module terminal B. Light Brown/black wire.
Terminal - D10 -DFI module terminal A. White wire.
Terminal - D11 - DFI module terminal L. Black/red wire.
Terminal - D12 - DFI module terminal D. White/violet wire.
Terminal - D13 -oxygen sensor RH side. Grey wire.
Terminal - D15- oxygen sensor LH side. Violet wire.
Terminal - D16- oxygen sensor RH and LH. Black wire.
Terminal - E1 - Auto trans TCC PWM. Brown wire.
Terminal - E2 - injector number 3. Violet wire.
Terminal - E3 - injector number 2. Green wire.
Terminal - E4 - injector number 5. Grey wire.
Terminal - E5 - Auto trans 2-3 solenoid. Green/white wire.
Terminal - E9 - Fuse #9, purge solenoid and heated oxygen sensors. LH & RH. Pink wire.
Terminal - E11 - ventilation system. Brown wire.
Terminal - E14 - Auto trans force motor. Grey/blue wire.
Terminal - E15 - Auto trans force motor. Red wire.
Terminal - E16 - coolant temperature sensor and throttle position sensor terminal B . Black/yellow wire.
Terminal - F1 - injector number 4. Brown/yellow wire.
Terminal - F2 - injector number 1. Blue wire.
Terminal - F3 - injector number 6. Yellow wire.
Terminal - F4 - A/C relay. Light Green/black wire.
Terminal - F5 - Check engine lamp. Brown/white wire.

Cheers for that mate, where abouts did you pull that from? Im keen for a full list. Now that i know its printed on the plugs ill have a closer look and see if i can determine why 2 wires were cut on the harness.

I got it out of a wiring diagram in a VS gregorys workshop manual .At least the wiring diagrams in the gregorys are readable.The hanes and max ellery workshop manuals are hopeless when it comes to wiring diagrams.Its got all the auto trans connections as well as a few other things.EDIT,Now its the full list there.
