Replacing Stereo in 2005 Yaris

[firestorm22]

Hi Guys,

I'm a newbie so I'm probably asking a really stupid question.

The CD/MP3/RADIO player in my 2005 Yaris YR (Australian model) has finally given up the ghost. Just says Error 1 everytime I try to play a CD.

So I went out and bought a nice Pioneer unit to replace it.

Basically I pulled away the plastic panelling and unmounted the current unit which was pretty easy. However I discovered the wiring for the OEM unit is completely different to what the pioneer unit wants. The pioneer unit came with wiring in case of this but the problem is I have no idea what the Yaris wires do. I need some sort of wiring diagram to figure it out.

Does anyone know where I might find a wiring diagramme for this unit?

Also when I put the factory OEM unit back in of course it activated the SEC security code which I have no idea where it is. Any ideas on this too?

Many thanks...Tim.
