No, I think A10 is an input, not an output, so you aren't going to see any signal there. To be honest, I am as much in the dark on this as you are. The only speedos I have ever run off the VSS signal were aftermarket, and those have their own internal signal processor.

If you are really brave, you could try connecting the speedo directly to the VSS output. The reason I said brave is that I don't know if the unprocessed VSS signal could damage the speedo. What are the chances of your getting a more complete wiring diagram for the burb so you could find out where the other end of the wire on B3 is connected?
