I used a multimeter and made a diagram of the pins in the connector on the car and indicated on the diagram which pin was which. In other words, turn on the headlights and see which pin is hot, turn on the high beams and see which is hot, foglights, etc. Note color of each wire.

THEN, use the ohmmeter to determine which plug in the headlight is which. Then pull the back off the connector on the car and move the pins around to match up.

It could be that someone here has a diagram that they can share, but mine was just scratch paper and I threw it away after I was finished.

Good luck,
