Hi All,
I am working on my armrest to shore it up(stip creaking). Once I got it apart I quickly noticed that it had a loom running up one of the arms? Looking in side the bottom of the mid tray I see a 3pin connector and what looks like a weird fiber-optic connector? Thinking USB and audio, but I do not see and molded blank areas. Anyone know what these are for? My donor armrest did not have these(there is a molded channel in the base of the mid cubby).

Could be for the optional connector that goes into the center console that has an Aux in, iPod connector and USB.
