240zzzap Posted May 18, 2013 Share Posted May 18, 2013 Is this wiring setup similar for the RB20? There are a few similarities but wiring the 20 is supposedly a bit easier - http://forums.hybridz.org/topic/90784-wiring-guide-for-installing-a-rb20det-into-a-datsun-z/?do=findComment&comment=860349.

rayaapp2 Posted December 17, 2013 Share Posted December 17, 2013 (edited) RB25DET NEO WIRING! 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 ECM RELAY 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! EDIT: 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. Edited January 28, 2014 by rayaapp2 Quote Link to comment Share on other sites More sharing options...
ZT-R Posted December 29, 2013 Share Posted December 29, 2013 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. Quote Link to comment Share on other sites More sharing options...

Wizzurp Posted March 4, 2016 Share Posted March 4, 2016 You want this guide, it's much more helpful if youve got a 20 http://forums.hybridz.org/topic/90784-wiring-guide-for-installing-a-rb20det-into-a-datsun-z/ 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. Quote Link to comment Share on other sites More sharing options...
Ba280z Posted April 2, 2016 Share Posted April 2, 2016 Need help. I'm trying to locate the wires on the same loom as my afm. This is the only plug I have and not sure which need constant and switched power. Quote Link to comment Share on other sites More sharing options...

Edit: Looks like this time I visited I was able to get all the images held ransom by photobucket. Whoever fixed the issue, THANKS!
