09 plate yaris sr wiring and aerial info

[wired2thebrink]

Does anyone know where I can get  info on the Yaris SR 09 plate wiring for stereos and aerial.

i'm trying to work out about the prefitted aux Toyota did and also about the aerial as to it being passive or amplified

 

[flash22]

It's the standard Toyota plugs for power and Speakers, the aerial is an amplified base 12v feed

what model stereo, some have the aux, some don't is it the silver one with the built-in vents - 86120-0D210

Does it have an aux button on the front ? if not you will need a CD changer adapter as there is no way to select the AUX input

the info what is about is for US Yaris's what has the aux button and 3 wire aux in on D74 (20 pin iirc)
