It was suggested by a member measure the resistance to figure the correct pin configuration.

I'm just tempted to match with the bixenons from top to bottom to the old xenons with the pins labeled 1,2,3,4

Also there are mixed messages as to ground the the 1st and 3rd for the high beams, S500 man grounded the 1st only, while zam2000 said don't do it.

I've been trying to tackle this but there are no resolution.

If anyone has the adapter/wire harness from autowerksdirect, I'll buy it from them or pay for that layout.

Seems like it's a hidden secret and no one is willing to share...hopefully some $$$ can help.

If I ever get this to work, I'll do a DIY for everyone

The new light (assuming you got the correct one cause there are two versions and many people make the mistake of getting the one with only two connections) should have 3 connectors (the other version only has two). Connect the original "headlight" connector from the car end (the oval one) to the center connector on both headlights. The other square connector from the car end is for the auto leveling system and obviously wont' fit into the new light cause the receptable is oval and not round. The company in SD that used to make these connectors are out of business and I bought one from them and consequently know the wire config. Worse case is that you solder wire onto the headlight pins and there are only 4 pins and tap the extended wire onto the wire from the car end connector. You don't need to cut the original round connector but rather you can get plastic wire taps and just crimp them on the exposed wires while still keeping the original connectors (if you need pics let me know). That's it and this will activate the leveling system. I'll take a look at my connection tomorrow morning and tell you the order. It's a vertical connector with 4 pins. They should match up to the 4 wires coming fromm the car. The leveling connector is the one closest to the side of the car or the 'fatter' end of the headlight. The remaining 3rd connector towards the middle smaller head of the headlight is not used but you will need to ground the first and last pin meaning you will need to attach a black wire to the first pin and then to the last pin and have another black wire coming out of the last pin grounded somewhere on the car or vice versa just make sure both the first and last pins are grounded. Do this for both sides. Without this ground, you will not be able to use the high beam HID. Basically you should have one short wire connecting the first and last pin and one long wire coming out of the last pin as the final ground wire. If you have questions, just let me know.
