Possibly Solved! Airbag Light w/ Aftermarket Seats

So we all know the situation, right? You install some really awesome new bucket seats knowing fully that the pesky airbag light will be staring at you when you finally take your seat.

Because you cannot buy the sensor mat from a Z4 -- there is simply no part number for it -- a while back I bought a sensor mat from an M3 hoping it'd connect. No such luck as the connector on the mat was roundish and didn't line up with the squarish harness in the Z4.

Fast forward to a few moments ago after removing the sensor mat from a Z4 donor seat. The plug coming from the Z4 sensor mat is the same as the one found on the M3! But that sensor mat first connects into a small black box mounted to the underside of the seat. That small black box then outputs to the squarish harness found on the Z4.

So, buy the M3 occupancy mat, buy p/n 65778367242 (the small black box), connect it all up and you should be golden! (After a code/reset, of course.)

I'm going to undertake this project this weekend so stay tuned!
