a6 , this is the spark read back pin, it sees the voltage via a voltage devider in the suppressor module, i have have a schematic.
the coil primary goes to 60v or more, during the firing point, (back EMF induction)
this huge spike would blow up any ECU, so the engineer, devised a voltage divider, limiting the size of the signal.
here it is.
the pin number varies by which ECU you have, for 10 long years,
