What do you need the harness for exactly though electronically? I know that realoem state it, but in a practical sense, why would a 11/09 halogen 125i model not need a harness and a 6/09 halogen 125i need one. Makes no sense in practical terms. Others have said you dont need the new footwell module or harness on pre 9/09 halogen models in these forums thats what us confusing theres no difinitive answer to it. Surely someone on these forums has tested it and on an EU 125i and either the bars havent lit up and they have needed a new FWM3 or its just worked and the blacklines have PnP. Thats what I truly need to know.
