The ignition line will have to be sourced elsewhere
as it is controlled by the GMLAN.

Check the fuse panel to the right of the center console for a source.

[Hint](Power windows work after you shut off your car, until you open a door!)

Power windows are retained accessory, which is probably interlaced with the dome supervision...that's not a wire you're going to want to jump. The BCM is in the same panel as the fusepanel...you can grab the main accessory wire from the BCM- that's going to be your best bet.

You can also grab accessory at the ignition harness



It's the brown wire there
