Fitting amplifier to Yaris head unit

[nish1979]

Hi can someone please help me with this. I'm still not sure what wire I should connect the remote too as there is more than one blue wire at the back of the head unit.

It also looks like all the speaker wire colours provided on the forum are not consistent across all models. I have a 2004 model in the UK and at the back of my head units I have 2 plugs fitted to it. One with 3 wires (blue, black and red I think) and the other plug with all the other wires. Does anyone have a link which shows a diagram of all the wires at the back of a toyota yaris head unit like mine which illustrates what each wire is for beginners such as myself.
I'm really worried about connecting the wrong wires to the high to low voltage phono leads as I'm scared that I may blow something when I connect them to my amplifier.

Thanks so much for your help on this.
