I REPLACED MY FACTORY HEADLIGHTS WITH NICE, NEW, EXPENSIVE HEADLIGHTS AND PLUGGED THE HARNESS IN AND VOILA, LIGHTS. SO I THOUGHT. ANYWAY, THE LIGHTS IN THE CENTER ARE THE ONLY ONES BURNING. I NEVER LOOKED AT THE OLD LIGHTS TO NOTICE, BUT SHOULDNT THE OUTER LIGHT'S BE MY LOW BEAM REGULAR EVERYDAY LIGHTS. WHEN I HIT THE BRIGHT SWITCH THE HALO COMES ON ON THE NEW LIGHTS, BUT NO THE BULB IN THE CENTER. DO I HAVE TO REARRANGE THE PIN LOCAIONS ON THE FACTORY HARNESS, OR DO I HAVE TO JUMPER SOMETHING, ETC. ALSO, I ONLY HAVE 4 WIRES COMING FROM MY ML350 HEADLIGHT PLUG, AND THE NEW ONE HAS 8 SPOTS WITH TWO MISSING. I RECENTLY BOUGHT A HID CONVERSION KIT, BUT TDONT HAVE IT INSTALLED YET, THINKING THAT WITH THE PLUG BEING SO EASILY REARRANGED, THAT I MIGHT ONLY NEED TOT MOVE SOME PINS AROUND. PLEASE ASSIST. ALSO, WHEN I BENCHED THE LIGHT WITH 12V, I GOT EVERY LIGHT TO OPERATE. ONE PIN, WHEN ENERGIZED, LIGHTS UP THE HALO AND PARKING LIGHTS, AND ANOTHER LIGHTS UP THE BULB IN THE CENTER OF THE HALO, AND ANOTHER LIGHTS UP THIS LITTLE BULB THAT SHARES THE SAME PART OF THE LENSE WITH THE INNER LIGHTS. PLEASE ASSIST. I AM SLAMMING MY HEAD AGAINS TTHE WALL.
