Putting this on here as well as 156 page as i may get more tech people reading this page.
starting off with car its one of the very late 156 2.5's made 2003 > with ecu 0261 207 597.
what i need is to find the Maf to ecu signal wire.
none of the pins on eLearn match with my car pins / wire colour . i have even found a ecu A plug layout where the pin numbers are listed top yo bottom ( pin 1 is at the top ) shown in pic as well with the normal 3.1 2.5 ecu diagram.
so all i need is the wire colour for the signal wire on the maf plug or a way to tell which wire it is etc etc.
my maf plug wire colours are 1,2,3,4,5 green/black // red/white // white // red white // white/black
the normal 2.5 ecu pins for maf to ecu are 25A / 54A / 57A / 63A / then 1 going to fuel vapour solenoid
my cars pins used for maf to ecu are 2A / 8A / 12A / 17A / 33A / 40A / 63A
so you can see nothings the same
please help this is the last step i need for wiring i've done all the rest for Ecu mapping
Which wire is the signal
green/black // red/white // white // red white or white/black
