Default apexi avcr & IAT wiring question

Does anyone know which wires on the ECU harness to tap into to install this? I need to tap into the following wires:

power
engine RPM (injector signal wire)
throttle signal wire
vehicle speed signal
2 different ground locations

For the IAT sensor, again, which wires do I need to tap into?

These are the last things I need before I try to fire my engine up!

so far I believe....

IAT sensor:
1 wire to 2P (IAT signal)
1 wire to any of the following- 2A, 2B, 2C, 2D (ECU grounds)

AVCR
power- 1A? 1B?
engine RPM-2I?
throttle- 1N or 2M? Not sure which one
vehicle speed signal- 1M?
2 ground wires (any 2 of the ones listed above)

injector signal- 2U or 2V? Not sure which one, if either*

*The manual lists an optional wiring method of using the injector signal wire instead of the tach signal, but says "the self learning mode will be limited in this mode when compared to engine RPM monitoring".

I believe I found the pin locations on my wiring diagram *(updated previous post), but I'm still unsure of a few. Can someone who's done this verify them for me?

If you have a NB, here's a resource. It's what I used when installing mine.

You will want to use the tach signal, not the injector. Watching the injector duty cycle is nice, not nearly as nice as boost-by-gear.

Yeah I'd like to monitor the tach.

Anyone have any insight into this??
