The wiring harness I have goes from the battery to the relay then to both HID ballasts. The factory fog light wiring on both sides goes to the relay to trigger the relay.
The part that you got does it connect directly to the battery?
Yes it connects directly to the battery. I had to install a harness in order to get my hi's to work, its the exact same harness. Its weird because it works fine when the truck is off but as soon as I turn it on they flicker.
