I removed my headlight on the passenger sided my 09 isf (so I could attempt to fix the ballast in my headlight) and I drove the vehicle while the light was out of the car, and the bumper was off so the pigtail connector that connects to the headlight went underneath my tire and destroyed the connector. I ordered a new one and got it in but now I need to know which wires go where and there are 22 wires that have to be put into the new connector. I don’t know if anyone has had this problem or not, but any help is appreciated.

Find the part number for your connector here, section D should have them all, illustrated and with pin numbers.
As for the pins, here's what I could find:




Missing 3 I think, unfortunately.
