On the passenger side, there was an illumination pin that lit up the light in the lock and windows button. That's where I was going to tap into. The drivers side didn't have that same pin. It must happen in the door control itself. I did find a wire there that only came on when the headlights were on, but I can't remember which one it was.
Unfortunately, nothing works quite like the pins 3 and 9 "ambient lighting" factory solution. That makes the leds come on anytime the door is open or the lights are on. The closest I could come to replicating the factory functionality was turning the leds on when the headlights are on.
It really stinks that they control the output on those pins with a code in the BCM.
