2wd Low lock kit install

[Moose2]

2wd low lock kit, where do I find the under dash pass through circuit. I have the upfitter switches. Maybe I’m blind but I ain’t seeing the plug or blunt wires under the dash. 21 3500 Laramie. Under hood, no problem, pretty much like my 17 but I can’t find the one under dash. I want to activate low lock kit via aux switch without sending a wire through myself. Thanks in advance.

If it’d been a snake, it might have bit me. Found connector up under dash by emergency brake.
