Yaris OEM Auxiliary Input (YarisWorld.com)
"The Sedan and Liftback use different Aux jacks. The part number above is correct for the Liftback (06-09). For some reason the LB one has a higher list price than the sedan one.
The Sedan one is: 86190-53010 (06-08) and 86190-48010 (09)."

Factory Plug Wiring
ALO: Aux Left Output
ARO: Aux Right Output
AGND: Aux Ground
ASGN: Aux Signal Ground
AUXO: Aux Output (switched input to HU to indicate that cable is plugged into Aux jack)
AGND is the shield, where as ASGND is the audio signal ground. I think they added the shield to the 09's to fix the noise issue that some people complained of in prior years.
