Found this plug attached to the top of the driver side footwell panel (the one that attaches to the knee panel under steering wheel). Any one know what it's for?
What's this 12 pin plug for?

I don't know what that's for, but I did tap into the orange wire for my power folding mirror controller out of convenience.
I took the end off of it and found this.. So all the wires are connected together.. Hmm. Weird...

Maybe that one orange positive wire feeds a bunch of dash components and that's just GM's way of splicing wires?

Is that the under dash data communication splice pack? The splice pack under the rear seat has an identical comb that connects all the communication module wires.
It does look like it is a splice pack for the BCM when i look into the wiring schematic posted on here.
Gotcha.. Thanks guys.. Just working on some footwell lighting and was like wat is this plug? Lol
There is a lot of weird wiring on our truck. Hell, while looking at the schematic for you to make sure that is what it was, I stumbled upon how I can tap into the RAP feature and use that if I wanted to. Still not sure if I want to with my system and would rather have it like it is now where its only hot with the key in ACCY or RUN but still cool that I found the wire I can tap into for it. haha.
Haha I may have to look that up.. Not for sure what I would use it for though... Damn u kickass.. Now thinking bout mod for the RAP.. Lmao
Haha. Sorry man. I have so much planned on my truck, it's just a matter of finding time to do it since I don't have a garage I can park inside of to work on.

When I took my dash apart to get the cluster out, on the back of the block off plate where the 4wd switch would be there was a 4 or 5 pin connector clipped to it.... I'm guessing they come with the 4wd harness whether they have it or not?
I apologize for going off subject. Just thought I'd bring it up since we're talking about mystery connectors lol.

I hear ya.. I'm working on mine outside since its fairly nice out here..
N garth.. Better watch the off-topic discussion.. I will have to lock the thread.. Lmao!

Guaranteed it's one of the two splice packs for data communication. They are brought together in those two shorting combs to enable troubleshooting a data comm problem. When you have a single bus that goes to the same wire and then ALL AROUND the vehicle to each of the intelligent modules, a wire short or bad module in any one place can take down the entire vehicle. To troubleshoot that sort of problem, you take out the shorting comb, then use a meter to check the wire in the connector that fans out to the modules for being shorted to ground or held at 5V. If you have none of that, then you can add one module at a time back into the circuit by using wires, or the ol' "Scotch Tape on one finger of the comb at a time trick" to isolate possibly bad circuits or modules.

Confirmed, Splice Pack SP205. Check the 2002 wiring diagram, under Computer Data Lines on page 22. All the wire colors shown there are on that pack.
Funny I just found this yesterday when I replaced my mode actuator and was wondering what it was for. Thanks for the answer before I even asked.
Glad to have helped in advance. Isn't time travel wonderful!
