Default Need help with VSS pinout on 4L80 swap. Thanks!!

Hey all,



Converting my 96 k1500 4L60e to a 96 4L80e. I have most of the pinouts figured out, but I have one question. I discovered that the VSS for the 4L60e is actually on the transfer case. This kinda threw a wrench into what I thought I had to do with the pinouts on the 0411. It thought it was going to be easy because I expected a sensor to be on the tranny.



To my question,



Since the 4L80e has two VSS sensors, do I just re-wire the VSS from the transfer case into the 80 and leave the sensor sitting there, unused on the transfer case? Based on the pinout spreadsheet I have from when I converted to the 0411, I have 4 wires to use on VSS for front and rear sensors. There WERE two other wires that were spliced together and inserted as a single signal for VSS as well, but there doesn't seem to be any instruction or explanation other than that. The spreadsheet calls out for one set of VSS wires to be 80 specific and the others to be 60 specific and then those two that are tied together.



Anyway, I may be over thinking it, but that's where I'm stuck. Do I leave the transfer case VSS out of the loop and tie those wires into the 80? Any input would be greatly appreciated! Attached 0411 pinout below.



Thanks guys!
