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 material are outdated tho'...

Here goes

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.

You want this guide, it's much more helpful if youve got a 20




I used that as a mini guide (with some changes) for mine and it was quite good. I had mine wired in like 20 minutes.

I checked archive.org for this thread and it has a few pictures cached, but not all of them. I guess it's better than nothing, right?
