Q45 side:
Brown and Yellow gt; Pin 21 on VH ECU
Black and Blue gt; Pin 22 VH ECU
White gt; Pin 47 VH ECU
Brown and White gt; Pin 31 VH ECU
Brown gt; Not sure, speedo?
Black gt; Body earth

Z32 Side:
Blue gt; Pin 21 VG ECU
White gt; Pin 22 VG ECU
Orange gt; Pin 31 VG ECU
Black and White gt; Pin 47 VG ECU
Green gt; Not sure, speedo?
Black gt; Ground

No guarantee that those colours are right on the VH side, I have a '93 Jap Spec motor and am trying to use '94+ US Spec Q45 diagrams. Pinouts appear to be the same though and the motor runs.

I've matched up the pin numbers for the 2 ecu's so that the VH Pin 21 is connected into where Pin 21 from the VG ecu used to go.

This is what Nick had in his VH to Z32 wiring sheet, and makes sense from the wiring diagrams I have.

I'm using a ECUTalk readout rather than the usual laptop connection. I have verified it work on a mates Z32. According to the ECUTalk people it has worked on VH's before (I've seen one working with my own eyes).

So what's the problem? Any suggestions.

I'm just going to try my spare ECU and see what happens...

Helped me diagnose bad injectors and adjust my tachometer more accurately already. Totally worth the money!!! One of the best investments you can buy for your Nissan period! Will be really useful on the dyno.....if I ever get it finished.

There is actually one or two wires listed in the consult diagram that you don't hook up. tmorgan4 2008-05-06T05:51:34-08:00 http://forums.nicoclub.com/zerothread?id=335286;postid=3625484#3625484 Nevermind, I found a diagram in the FSM.
