Would anyone know what the Yellow/Black wire that goes to pin 6 on the 26pin plug on a JDM W6 ECU is for.
Came across this link www.suberdave.com/subaru/glwrxt/Wiring/JDMandUKWiringDiag.pdfvia NASIOC, but the wiring diagram is slighty askew it says pin 6 on the 26pin is Lg (Light Green ?) and pin 5 Yellow/Black. My ECU has Light Green on pin5 and Yellow/Black on pin6.
Not sure if something was lost in transalation from Japanese to English, or whether Subaru decided to swap a couple of wires for no useful reason.
I can't track the wire back as it is part of a loom install into my kit car
Thanks for any help

 

A bit (ok a lot) of googling came up with.
ok. who actually knows ej20K electronics and ej20G electronics well? [Archive] - NASIOC

The diagram the previous post linked to didn't make sense. It looks like the wire is part of the 5th injector circuit. On my loom there is no wire on the engine side of pin 2 on the 16pin engine plug. I guess as I have no 5th injector there is no need for the wiring.
