I used a multimeter to quadruple-check that the pin numbers are identical for my OBD-II-to-DB9 cable I'm using for the main CAN bus (the one that works) as they are for my custom radio harness to DB9 cable that I'm using for the CAN-B bus (the on that doesn't.)


You write as if A and B are physically separate busses. Is that really the case? Or are you just talking about the differences in the connectors?
