Assist with identifying wiring connections?

[peternguyen]

I removed my radio and found these 3 plugs unconnected. Car runs fine with no issues or warnings so I don't think they're important. But I'd like to know, if anyone here knows what they should connect to?

A) 2 prong plug - brown/white & blue/brown/yellow
B) 4 prong plug - brown and white
C) 2 prong plug - brown/orange and 2 wires that go into one: purple/brown & pink/green/yellow

Thoughts? Do any belong to the OBC?

It's common for these cars to have unconnected harness points. The cars were built with standard wiring (for the most part) so low optioned cars have lots of unconnected points. There are electrical diagrams online that would likely answer your question.

you can check in the ETM by built year under component location views, there all plugs are shown and their locations and for what they are http://shark.armchair.mb.ca/~dave/BMW/e34/

I think the ETM is very hard to use for this purpose. It does work but requires a lot of manual scrolling and needle-in-a-haystack effort, and then there's the 2% of the time it's slightly or very wrong.

At least one of those plugs is for a telephone.
