When you unlock the car, the GM5 sends a command to the LCM to turn on the dome lights.
Is this why whenever I take apart the steering wheel the steering wheel buttons seem to all run on like 2 wires going into the car?

I mean all 6 buttons for music/bluetooth and 4 for the Cruise control all seem to run into the car via like 2 wires.
