Hey everyone; I am building a specialized prototype car and I am trying to incorporate a homelink setup from a 2004 Audi TT. I have the three button head unit and the control module from behind the bumper. I also have a wiring diagram. What I am unclear about is what are the pin numbers for each of the connectors. I don't have any wire harness or pigtails associated with either of these.
I plan to make my own connectors and just need to know which is pin 1 on the head unit (looking at the plug with the buttons facing up) and what are the pin numbers for the control module (looking at the plug with the Audi label on top). If pin numbers are unknown then what are the wire colors for those same pins.

Any help is greatly appreciated.

Thanks so much
Colin
