I have '12 300 S without factory HID's I went with the DDM 6000k 35w 9006 bulbs. They are bright and i like them but would rather have 5000k to match the DRL better.
The setup that worked was just BOW3 adapters with the headlamps. There is no need for a wiring harness. With the wiring harness hooked up it made the lamps flicker.
However the foglights need a wiring harness because they have intermitten firing issues with out the harness.
