Headlight diagram

Hello all!


Thanks in advance for any help I’m having a nightmare fitting some aftermarket headlights. The pins are all in the wrong place and I’d really appreciate a hand.

I have a 2013 pre-lci headlight with pins in positions 2, 3, 6, 9, 10, 11 and 12. The seller is asking me to find out what each of the pins does. Does anyone have a diagram or a list of what each pin does? Thank you!!!
