2006 A3 tail light pin out, wiring colors

[vtraudt]

Can someone link or post the pin out for the left and right taillight of my 2006 Audi A3?*
Connector has 4 wires. Brown ground. The other 3 should be turn, light, brake? But which is which?

My test light does not work for some reason, and my digital multimeter either; seems like car is 'shutting down' the connection if taillight is not plugged in (or not correct resistance sensed)?

Figured it out. Opened the tail light and trace each bulb (turn, brake, light) to the respective pin on the connector.
