Is this wiring setup similar for the RB20?
There are a few similarities but wiring the 20 is supposedly a bit easier - http://forums.hybrid...-z/#entry860349. Links to ref. material are outdated tho'...

RB25DET NEO WIRING!
I have a 2000 RB25det.
I removed the ATTESA system. I cut it out and removed the wires going to the ECU. There are a small bundle of them and a relay. If your not keeping it and you probably wont for a Z, cut or tuck.
Pin 5 GRY/RED Start Signal
Pin 17 GRY?BLU MIL to 12V switched on a 10A fuse
Pin 20 GRN/ORG IGN Switch 12V
Pin 24 BLK/PNK FP Signal to 12V on the other side of the Relay(was not integrated into the EFI harness
PIN 31 WHT/BLUE IGN Switch 12V
Pin 6 WHT/GRN B+ 12V
Pin 1&3 WHT/BLK B+ 12V
They should all have 10A fuses to each power lead according to the FSM. The Start signal should have a 10A fuse as well!
I am running!
I missed 1 wire that is critical.
In the bundle of wires with the big white connector near the Relay packs there is a solid BROWN wire. This is the POWER wire for the IAC and the VCT! I was up and running without this and it took me until today(nearly a month later) to realize I had no VCT, but I also only drove it a handful of times. I then re-adjusted my idle and TPS and I am off and running.

I have a .4 amp draw on the alternator, does anyone else have this problem? I have tried 3 other alternators. I used the diode as mentioned in this thread, do i need a bigger one? I am using a Quest 125 amp, or whatever it is i cant remember.
