Thanks, it'll be just a few moments while I pull the info.
Thanks for your patience. At the VCM it's going to be
Connector C1 (blue connector)
Pin 29 - light green and black (low)
Pin 30 - purple and white (high)
So sorry got the two mixed up. Just a moment and I'll get you the right one
I'm unable to find the input let me open this back up to other experts for you.
I have checked your research, you are correct with C3 7 & 8.
That is of the PCM of the original 4L80E.
A 4L60E does not have an ISS, only a VSS.
So which PCM are you planning on using?
I would assume you are using the PCM for the engine and transmission you are fitting?
Do you still need help with your problem?
