Coil Pack Low Reference....common between banks?
On the E40, 1,3,5,7 goes to C2-16 and 2,4,6,8 goes to C2-64.
The question is; is that a common ground location within the ECM? Am I going to run into any problems if I don't split up the low reference wires to be paired with the correct cylinders after the firing order change?
I know on the 411 PCM, the low reference wires don't seem to matter. I just need to make sure it works the same on the E40.
Will codes be generated if the circuit doesn't return to the correct side? I hope this makes sense. Thanks.
