JDM ECU Pinouts?

[Tricky-Ricky]

Has anyone got a JDM ECU Pinout diagram with wire colours if possible, as it might be closer to my JDM 350GT Skyline than the US infinity G35 and US 350Z manuals that i have, as nothing seems to match up or is not what its supposed to be.

This may help.

 

The image of the ECU pin module has not copied so I can email it over if you wish.

Thanks Alex, the only differences to the manuals i have are pins 34 and 35 which are supposed to be IAT and O2 signal for no1 bank 1 (not confirmed this yet, but the IAT is actually behaving like the coolant temp sensor so i guess it is on mine.

 

50 is not TPS on mine wrong value, and i don't have 51, but have 52 which is the right colour for the MFA but again wrong value, and i am guessing pin 73 is probably my IAT

 

I also tried to use 62 for RPM but the LM-2 wont see it? the JDM 350GT ECU is obviously completely different

 

I really don't want to have to go through it all with a meter
