PLEASE HELP!!!
I recently purchased headlight assembly units off a 2004 BMW 525i to replace those on my 2005 BMW 525i. There are two issues:
~The 2004 has 2 plug-ins, the 2005 has 1.
~The 2004 main plug-in has 8 pins, the 2005 has 7.
What do I need to do to make this work?? 2005 525i Headlight Assembly 2004 Headlight Assembly
They are not interchangeable. The one you have was replaced in 08/05 and stopped being put on cars after 02/05. For it to work it will cost you more time and money than it's worth. What is your build date?

It would most likely require running about 6-8 new wires from the headlights to the cabin, plus a new headlight module, and AHL control module. They would also require some coding to the vehicles as well.
