I plan to add an Alpine (or Pioneer) navigation system
to my W202. The system has a vehicle speed sensor
wire and I was wondering where it should be connected
to inside a W202. I was told that I could use the
volume dependent wire behind the factory MB radio.
If this is incorrect, where can I find the correct wire?

Thanks in advance for your help!
 
Pin 1 on the Radio ISO plug is the speed sensor signal, I believe.
