I am trying to tap into the high beam circuit at the stock connector for the projector shield solenoid ( working on the Bixenon Retrofit ) but the stock connector has three pronged.... anyone has the diagram to tell which Wire is for the high beam and which one is for the low beam ?

Thanks in advance !!!

 

Source the ground wire , usually Black lined . Then the other 2 is low beam power and high beam . As long as you get the ground correct , the other 2 can just be switched .
