Hello this is my first post here and it may not generate any answers as I have searched for the answer to no avail. I have a 750li that needs a wiring harness replaced. All I know is the location. It is located on the passenger side behind the headlight. Does anyone know what this part harness is referred to as or the part number. Dealer wants $1500 for the part and $2000 for install. If possible I want to avoid that haha. Thanks in advance for any answers.
