Re: 4 speed auto. Convert to tap shift?
I would take a closer look at the black wire between the plug and ground. Switch the multimeter to ohms, and set one probe in the plug end (G) and the other probe to a solid metal body surface. There should be no resistance, it should be a direct short. If the meter doesn't react, your problem is there.
If it does react, then your shifter and the connections appear to be fine. I have absolutely -zero- knowledge of the functionality and programming of the TCM, So that would be where my help in troubleshooting comes to a screeching halt.
