I don't know what yoy guys many, i bought 2 different connectors per unit by my dealer, 1 connector goes to the wire from te car and the other connector goes to the LED light, i just connected pin 1 from the car wire to pin 1 from the connector of the LED light, and also pin2 >> pin2 and Pin 3 >> pin3

Just a connection between an existing thread and the new LED lamp
