I'm having a little trouble with my wiring for the Consult port.
This is what I have found.
Q45 side:Brown and Yellow > Pin 21 on VH ECUBlack and Blue > Pin 22 VH ECUWhite > Pin 47 VH ECUBrown and White > Pin 31 VH ECUBrown > Not sure, speedo?Black > Body earth
Z32 Side:Blue > Pin 21 VG ECUWhite > Pin 22 VG ECUOrange > Pin 31 VG ECUBlack and White > Pin 47 VG ECUGreen > Not sure, speedo?Black > 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...
