    Question Identify this; Underdash sensor?

    Hey I was cleaning up the car a couple days ago and came upon this sensor. I tried searching and came up with nothing, considering I have no clue what it is I didn't know what to specifically search for.

    Heres a pic of what Im talking about:

    Bump, I have no idea what that is.

    Maybe ask EAS, they know this electronic stuff pretty well.

    Yeah I'm just really really curious. It has two black wires that come to it. Kinda odd.

    That is the fiber optic connector. They connect to that along with the OBD connector (if I remember correctly) when they are doing programming on the car at BMW.

    The whole canbus system is accessed this way..allows the SSS to communicate with all modules and code them faster.

    If you think coding a car in 6-7 hours was slow, I wonder what it would be like without the fiber optic cable.

    I was looking under there myself today and noticed a small 4ohm speaker under there as well. What is that for? I unhooked it hoping it was for the seatbelt/ice/parking brake/ everything else in the world chime, but it wasn't.

    The everything in the world chime comes from the audio speakers if you have a CCC or CIC audio controller. If not I do recall it being in the cluster.

    I guess the 3" speaker is for all of the massive bass that the L7 stereo puts out! Honestly, I have no Idea. I'm guessing that it's for that SOS feature?
