That's wild. The torque mount for the BSM engine does not have any electrical connectors or sensors. Just a dumb mount.

According to my parts catalog both BFM and BSM have the same part nr, new replacement ones dont have the connector in the mount, yours may have been replaced one time already. My parts sources can be wrong though.

I looked all over and didn't find a harness plug or anything related to that mount ever having a sensor. In fact, that mount I took out is the original from 2007. No sensor or wires. Weird. Maybe there was a cut off year in production where they deleted the sensor on the mount.

That sounds like a possibility. Strange, because the purpose of the active mount is to dampen the vibrations while low rpm, aka luxury stuff.

TSB from 2008 mentions "Electrical solenoid valve N382 is no longer used on Engine Torque Support Bearing" and listed all Vins for the 2003 and 2004 models, and then up to Vin 005513 for the 2005. So I presume that was midyear 2005.
