Hey guys! I'm new here, so I hope I am not renewing a previously discussed topic...

I have a Becker Grand Prix in my 89 300E. I want to remove it and replace it with an Alpine head unit I have. I have looked at the wiring and can't figure out some of it. The power harness is easy enough but there are some I can't figure out - I assume these may be related to the anti-theft or speed-volume functions?

If anyone has a wiring diagram I would really appreciate it! My e-mail is [email protected]

Thanks!

p.s. nice page Alex! I did check out your post, but my unit is a little different...
