BTW, why do they call them bi-Xenons? They only have a xenon low beam. I know it aims up when the highbeams go on but the older xenons (01- 996 and boxster) did this too. Does this mean I already had bixenons in my 2000 Boxster S?

For anyone looking to use the above headlight pinout as a reference, the numbering doesn't match the numbering used by Porsche on the headlight... its backwards. I just did this on my 2000 Boxster S, and if you look at the connector on the back of the 02+ headlight, the numbering is correct as show in the picture, but the wiring is reversed. Conversely, if you look at the face of the connector, the wiring layout is right, but the numbering is wrong. Just a bit of trial and error with a multimeter to figure that out. Looking at the back of the headlight, the connector is as follows. |------------------------------------------| | # 7 | # 8 | # 9 | #10 | #11 | #12 | | # 6 | # 5 | # 4 | # 3 | # 2 | # 1 | |------------------------------------------| #1 Turn signal #2 Side marker light #3 Fog light #4 High beams #5 Not connected #6 Common ground for above lights #11 Xenon low beams #12 Ground for low beams #7-10 are for the self leveling, on my Turbo headlights, there is a HELLA leveling motor, and the internal wire coloring is #7 = Blue, #8 = Orange, #9 = Yellow, #10 = Pink. My old headlights (01- litronics) had a Bosch leveling motor which looks exactly the same, but the wires are different colors. It would seem that the wiring color converts as follows: HELLA vs Bosch: Blue = Green Orange = Red Yellow = Black Pink = Blue The 01- headlights have the self leveling wiring on a separate 4-wire connector, and the coloring is from top to bottom Blue/Black/Red/Green (I have to check on the numbering order 1-4 or 4-1). I haven't actually tested the self leveling yet, but I assume (hope) that the Bosch and Hella motors are interchangeable. I couldn't find a used set of wiring harnesses, so I made up an adapter cable with 0.110" insulated spade connectors and 14 awg wire. 14 awg was totally overkill for most of the wiring, but it was easiest to just do them all the same for me. If I can find a used harness I'll switch over to proper connectors. Hope this helps someone...

Is there a part number on the plug for the headlights? A bosch part number maybe? I am upgrading my 2000 Boxster S to the 02+ 996 front end, and really don't want to have to buy the entire wiring harness. I have litronics from stock, so I'm hoping the auto-leveling will carry forward.
