I want to add some LED lights under the steps on my Tahoe and was wondering if anybody knew where I could tap in the BCM wires under the driver's side dash so they would come on/off when the door opened/closed? I did this on my 24 Sierra Denali but know the wiring is more than likely completely different. Thanks!
21+ Tahoe where to tap for step lights?

Perhaps figure out where the illuminated sill plates are wired from...maybe even locate that accessory wiring harness...that is probably the closest to on/off w/ the door.

That module (BCM) is located under the dash on the driver side. Remove the carpeted close-out panel and look up in there to see the module with the connectors that match what's shown in the diagram.
Yes, however this ties into a harness that get power from the battery and plugs into the OBDII port.
