Transmission Range Sensor connector wiring issue?

This is awesome, thank you so much!
I do have one, now it seems weird, question: would you have any idea why my TRS (NSS) would have had a 7th wire in addition to the 6 in the provided image? I've attached the poor, photo of the connectors original state, I. E. Before I began any cleanup.
As it stands, I guess I'll just attempt to replicate the diagram, but it does leave me a bit concerned (as with most everything on this infernal work vehicle).

Thank you very much again!

Sorry one additional thought, now that I'm physically looking at connector: all of the "not used" seats have a solid plastic barrier preventing, I assume, moisture, or incorrect placement from getting through. It's definitely possible the previous Dr. Frankenstein type of mechanic / owner punctured it while adding a superfluous? 7th wire but it sure adds to my confused concern.

Thanks again by the way!

Sheesh I apologize but if it helps, the 7th wire in question is white and black and at least does seem to originate from the same branch of the feeder harness.

I really appreciate your reply and time, but now I'm a bit more confused; I actually did see that diagram before but you'll note that the first diagram you sent me had only 6 wires coming to connector, and I have all 6 of those colors / open pin seats (with no white / black wire indicated) but then the bottom diagram seems to show only 5 wires, now including the w/b wire and seemingly with just 4 of the others, but in a different order?

Ahhh, thank you so much! That makes all the sense now, I truly appreciate your assistance, and patience! I'll confirm the fix tomorrow but I'm certain we're in business now.

Hello! Well, this issue continues to be a thorn in my side (I've just been so busy working I've had no choice but to use a wasteful rental).
Anyhow to date I ended up buying a brand-new connector harness, and ultimately a new TRS, all installed extremely carefully and to spec (including numerous shifter, alignment adjustments until exactly perfect) yet the dreaded flashing OD/limp mode continue.

I just ran through a multimeter diagnostic I found (see attached) and see what I believe to be the issue:
While in park the White/Black wire, TR4, reads 9volts instead of 0 as the chart indicates it should. I followed back and saw no signs of even a chance of any further wire frays or the sort, as I'm mediocre at best when it comes to electrical, I hoped you might have some semi specific steps for me to figure out why the errant voltage.

I should add, one main reason I'm confident of the install is dead center shifter alignment, starts only in P or N, and reverse lights illuminating only in R.

Please let me know if I failed to provide any necessary info; and thank you in advance, and retrospectively in fact, for all of your help, it is super appreciated!

No. It never was (though I did read a similar post where that was the case), in my case the worst the new install ever seemed had all notches about half a letter shifted to the right of each dead center respectively.
This has been rectified with some slight tweaks to the shifter cable along with the Transmission Range Sensor. Now all are pointed perfectly dead center when shifting up or down the tree.
