You will use the front one for sure, near the bell housing; it's the iss, input speed sensor.
Use the second vss on the transfer case.
Ignore the the sensor or plug on the 80e tailshaft.

That will get the trans and engine working together, shifting.
Then use the vss output wire from the PCM to the speedometer.

Ive had the truck running for almost 2 years now, and just dealt with the issue. But now Im ready to dig into it. I called a long time ago and I think I spoke with Ray about connecting your vss connector (new style) to my old transfercase. Since the 2 have different plugs, He said cut my OBS pigtail off and put it on the nelson harness. Was that correct? Thats what I did, but it never solved the problem, and I kind of just forgot about it.

Ya that should work. Should be the same type of sensor just different looking.
Any dtc's?
Like wrong gear ratio or input signal?

The only code I get is Vehicle Speed sensor circuit. Cant remember the number.
I plugged nelsons vss in the back of the tcase and it will shift by itself, but then my speedo doesnt work
