Can someone please help me, sorry if you've had this but I've searched and cannot find answers.

I have a octavia vrs mk1 '04. I want to change the symphony stereo.

I have a new stereo and also have the required wiring harness.

I took the stereo out but dont know what the green/yellow/blue plug is and where it is to go as on the harness there is no plug for it.

Is it the cd changer wires?

Im sorry if its sooo simple but Im changing a stereo for the first time.

Thanks for your help.

I can't say I took any notice of what was behind mine when I changed it, but all you need plugged in are the two ISO connectors, one for power, one for speakers (the two female connectors on your harness) and the aerial.

The other plug can only be your changer which is now redundant!!!

Hope this helps.

Thats great, I didnt want to just change it and press play in case something went wrong.

I will change it 2mrw.

Cheers

look here for an explanation of the plugs and wires - that link is for a fabia but the octavia is the same.
