I had a new head unit installed in my 420 sel some time ago. At that time I didn't know Becker was still fixing the original radio. Since then I realized that I could have the original radio fixed so now I have the original radio in working condition and need to reinstall it.

So I'm looking for a diagram that I can use to reconnect the fader control and the original head unit. I have new speaker wire with new speakers so those wire colors are not accurate any longer.

Any help would be appreciated. If I've overlooked a thread, please redirect and I will be happy to follow up on it. I have contacted Becker directly and they said they could send out what they have but I haven't received anything to date so I'm working on "plan B" in case that doesn't work out.

Thanks in advance for any help.
