Morning All,
I am trying to find a used mirror assembly on ebay but there are many variations. I have a 2005 S40 T5 AWD the dealer says the assembly i need is 30744589 but couldn't tell me if this was a 7 pin or 9 pin harness, I see both on ebay. would either work or would it throw codes if the wrong one. Any help would be greatly appreciated.

 

I'm guessing that the one with the most pins would mean that it's heated AND it's power operated...not sure if that helps you though.
