I have done LCI conversion on e90 rear lights. You don't need a harness just coding for hyper blinking. Mtranz helped me with that. U just need to rearrange 4 little simple wires to match the LCI order or wiring. Do some research on the forums. That's how I figured it out. I'm happy to help anyone I can. They work perfect without any harness.
