Questions regarding 2 R34 ECU pins

[CowboyZbop]

I know there are probably over a 100 posts regarding ECU pin outs between various sites and I have looked through everything I could but couldn't find what I needed. 

What I am having trouble with is identifying the purpose of a couple of pins of the R34 ECU. This is for a swap into a Z chassis so everything has been wired in as a standalone motor. All new fuses and relays before the ECU.

It is currently running but I know I am missing power to basically all sensors out of the firewall. IAC, VTC, AAC, thermostat, etc. I know I've damaged an ECU so I'd like to make sure I have power going into the right pins of the new ECU.

Pins in question..

• Pin 72 - Control Unit Power (Does it receive 12v ignition like pin 67 - Control Unit Power Supply?)
• Pin 109 - Control Unit Power Supply (Counter-electromotive current feedback circuit) Input or output?

Also I'll place this here to fact-check me that these are the major pins needed and that they are being connected correctly. The diagram is easy to see what needs to be grounded but should I be sending 12 volts anywhere else into the ECU?

• Pin 24 - Ignition Switch - 12v ignition
• Pin 67 - Control Unit Power Supply - 12v ignition
• Pin 80 - Battery Power Supply - 12v constant

Also interested in RB25DE ECUs or a stand alone for that model.

I don't have the wiring diagrams with me (I'm 3 minutes from getting on a plane).....but the wiring diagrams show you what the pins are connected to. The feedback one, I think, comes back from the ECCS relay.

Ah, it's always something silly. I don't know what wiring diagram I have but after another quick search I found one that references the R34 Neo. I think I can make heads and tails of what I'm looking for now. Have a safe flight, my friend.
