Body control module cable?

I changed my heater core and had to wait on parts from start to finish. All went as well as can be expected since I am not double jointed, but I still have one puzzle. I have a connector hanging out that I simply can't find where to plug in it in. It is a black rectangular connector with Lt blue, black and purple wire. Manual says it goes to BCM ?
I thought BCM that was the 3 by 5 silver box behind passenger side kick panel, but it has a larger cable plugged into it.
The pigtail I'm talking about is located behind the glove box originating at the large connector where the dash harness plugs in.
Someone help me with my brain fart, please.

Thanks!

What year is the vehicle? TCCM, (transfer case control module) is behind the passenger kick. BCM is located just left of the ash tray, left side of tunnel. Can you post a picture of the connector?

Thanks, I had modules confused. It is a 2000 Jimmy.

Have a picture but when I follow the FAQ instructions to User Control Panel, my screen doesn't show a "Album and Pictures" link to create an album from.
Not sure how to post picture.

Thanks

Update- It is a 12 cavity connector with the 3 wires described above. Believe it is the BCM cable coming from bundle to engine compartment RF behind dash. I figure it plugs into a connector from BCM behind dash. No luck finding it so far behind dash. May have to pull dash back out to find it?

Cable I was confused about went to the top of the heater box. Hard to see after dash is installed.

That one is solved.
Now...
No loose cable ends that I can see but headlights only come on if I pull the turn signal stalk back, the heater controls and interior lights still not working.

Turn signals, parking lights, brake lights all work when I turn on manual switch on dash.. Engine cranks OK and gauges work.

Starting to look at fuses, but can't help thinking I've missed something common to above.

Grateful for any suggestions.

There are so many connectors involved, you'll probably end up pulling the dash to find the problem.

Yep, found a connector near the headlight switch under dash I had missed. Now just iron out a vacuum line or two and should be on my way.

Thanks!

Glad you found it, and thanks for posting back.
