Re: LSx Coil Driver

I am plotting my wiring for this LSx Coil Driver Box on a VS V6 Commy at the mo.
Recently I have had a Kalmaker 2 bar Map tune done on the car & at the time the original T5 manual ECU/PCM was replaced with a VT auto ECU/PCM due to some PAL license code not coming back in time during the real time tuning.
Anyway everything seems to be running ok still.
Now on the instructions for the Coil Driver box... I would like to know what others have done when fitted to a V6 VS.
Loom 2 Red wire - this needs to be a switched ignition voltage. As I intend to mount the Driver box in the cab near the ecu, where can I take this from ? On the instructions it suggests (if I had a VN ECU) I could use the ECU ignition voltage [Pin A6 on an "808 VN ECU].
Can I assume that the current VS/VT auto ECU has a Pin with the same ECU ignition voltage as the '808 ECU ?
Loom 2 Black wire - Ground - Should be located at the same point as the ECU. If I had a VN ECU that could be [Pin A12 or D10 on an '808 VN ECU.
Can I again assume that the current VS/VT auto ECU has a pin(s) with the same duty as the A12 & D10 on the '808 VN ECU ?
This one also concerns me as I read that the VS ECU wiring had some issues with poor grounding wiring at times.
Bare with me, last one
Loom 2 Green wire - RPM - this can be any source that provides a square wave signal of the engine RPM. Where would I find that on the VS V6 loom ?
I see people refer to a single brown wire in the engine bay loom on the passengers side near strut top area for hooking up a Tacho. Is this a square wave output for engine rpm ?
Again on the instructions if I had a VN ECU I could use [Pin B5 on an '808 VN ECU].
Do I once again assume that the current VS/VT auto ECU has a pin with the same duty as the B5 pin on an '808 VN ECU ?
I think I already know I am going to get told don't be so f-ing lazy & find a VS V6 ECU wiring diagram lol.
Cheers
