For dumb people like me, this method requires a segment swap via HPTuners or the like?

So realistically this could be done with any of the three options for the primary, just might use a different wire at the ecu.

Exploring Alternate 1 and 2

Alternate 2:
Remove brown wire from pin 2 in Red/Green connector
Remove white wire from pin 79 in blue connector
Insert white whire into pin 2 of red/green connector

Brown wire moved to pin 22
Remover tan/blk wire (T) remove from pin 42 and move to pin 23
Brown wire is used as pin A in speed plug
Tan/blk is pin b in speed plug
__________________________________________________ ___________

Alternate 1
Or cut white and brown and solder brown wire to remaining white at trans plug
Wire white wire to pin A in speed plug
Tan/blk to pin B on speed plug

Remove pin 79 white wire and move to pin 22
Remove pin 42 and move to pin 23

Can I resurrect this one from the dead?? I'm in the midst of swapping a 80e/246 from a 2003 2500HD into my 2002 Tahoe Z71. The trans I have only has one VSS on the side, t-case has 3 on it. I can't find a definitive "yes" for this question on all the sites and forums - do I need install the second sensor onto the trans in order for this all to work right? Everything I'm using was pulled form 4wd vehicles. Thanks to anyone that can help!!

no, since its 4wd the rear speed sensor is on the output shaft of the transfer case
