Hey guys. I just tried to order a harness set on eBay.de but they rejected my order and said the harnesses do not match my car. They said my outside lights have a 4 pin connector and the euro one only has 3. Is this the harness I need to get my OEM euro led tails installed? Details are below. Any help is very appreciated.

LED tails:
8K5945093K
8K5945094K
8K5945095K
8K5945096K

I have a 2009 Audi A4 B8 S-Line with halogen tails.

Trying to retrofit the above tails into my car. I need the harness to complete so I can hopefully get David to code them.
