I got a response from Seicane this morning. They didn't mean the CD player. They meant the original tuner so I have to wire it into the Seicane harness in the rear. I have already removed the wires from the blue plug to wire the IBUS. I have to put them back. Problem is I don't remember in what position they should be. In what slot does the brown wire go? In what slot does the red/green wire go? Also, which wire in the blue connector is the CAN wire?
