Sorry to crosspost but info from audio forum doesn't look promising.


W203 Alpine/Bose Pinout
Anyone have a link (or whatever) for the exact rear pinouts for
the A, B & C connections on 2002 W203 an Alpine/Bose Cassette HU? Many post the Becker 1492 which is "close but no cigar".

Done tried the search and surprisingly came up totally blank.

Nobody knows the pinout for their radio?

Well if I knew what you meant by pinout I might be able to help you, but I don't. Can you please explain for the ignorant?

This is the meaning of "pinout"

A pinout is a description of the purpose of each PIN in a multi-pin hardware connection interface. The description can be entirely in text, often in table form, or it can be an illustration.
Not all pins are used in every connection.

So for me, I am hoping that someone knows the actual signal names locations on the various wires going into the 3 or 4 connectors on the back of the radio..... So far it is looking like nobody does.

He is looking to see what signals are transmitted over which pin, voltage or ground. He might also be looking what the state change is when a function gets activated; i.e dimmable lighting, remote turn on, etc.

Hope that helps.
