If they got the wrong connector the rest of the pins may be there and wires spliced and you could get the right connector and then wire that one in?

Yeah I checked behind the connector and the wires are all taped up right to the plug, none are missing out of the plug or falling out. Not sure if from the factory they taped them up for that short 3” run from the main harness, it thinking they’re in there somewhere and never got plugged back in because someone didn’t know where they went on a rewire

I’m thinking I need to unwrap those wires and pull the cover off the main harness and see if they’re wrapped in somewhere. If I could figure out where the CCM and SIR lines originate I can trace them that way too.

Good call. Gotta go exploring. If you know for sure the other connector was in there to begin with then the wires have to be there, IMO.
That could be #8 missing if the truck was originally made with the connector in my #9 post.
Yea, where I found it, it was not clearly marked. Sounds like you have some exploring to do. Oh joy!

Away!
Dont forget that those 2000 OBS trucks (Tahoe Limited, Z71, Yukon Denali, Escslade) were weird ducks.
I may try to find an upfitters guide for one of them. Or maybe for a 99? @Doubeleive, @swathdiver, @wjburken? Anybody know where to look for those?

should be here under 2000 current c/k 1500, or look at the 99's should be the same for the obs
