I am a little confused but the system on my 70 Charger used its factory headlight door relay, and the Painless H4 conversion kit for the Hella's I installed. I put the male Painless pigtail on to the factory female pigtail on the left headlight (where it comes from the headlight switch)...and the Painless kit has two female |_| pigtails that go to each headlight beam. When you turn on the headlights, the motor rotates the doors open and turns on the headlight beams. It was a 15min. install
