I have a 2002 2.7 with the BOSE sound system, and got a TR7421UB Continental radio with the BergvillFX adaptor, but the adaptor isn't right. I can plug the factory harness directly into the new head unit, and everything seems to work with the minor exception of getting no sound. If I try using the adaptor, the connectors aren't right.

The A connector (black) plugs into the adaptor harness, which then plugs into the head unit, but the B (brown) connector on the Bergvill harness is a different type of connector (see first picture). I'm pretty certain that I have the M490 Bose system, and not the MOST system. The second picture shows the stock harness coming from the car.

Anyone have any ideas? I'm hoping that I'm just a bonehead, and am missing something obvious.
