96 tahoe 4l80e wiring problem

[lummy]

Hey everyone,
I'm just about finished with swapping out the old 60 for the 80e. One thing I'm stuck on is the wiring for the new speed sensor to the pcm. The wiring diagrams I've seen say to put the pins in red 22,23 but I already have 2 wires there. I've also found an article that says OBS used white 7 and 8, but I have a pin on white 8 as well.
Anybody have a wiring diagram for a 96 HD that I could look at or run across the same problem?

Thanks

This is for over 8600 GVW so it should be the4l80.

According to the 96 file I have,

RED 22 and 23 is for the IAT and ETC signal.
WHITE 7 and 8 is for 4L80e VSS high and low signal.

That's for the ''blackbox'' PCM


If you've switched to the 411 PCM the pins are RED 22 and 23
