Installing Amp 53 Reg Yaris

[e11smt]

Would I have to take apart the dash to install an amp like in this tutorial?:

To get to the stereo wiring to wire in the adapter?


Also, is there a proper full tutorial somewhere of installing all the cables in this phase 2 53reg yaris?

Thanks!

Forgot to add also, how do you remove the glovebox in the phase 2 Yaris?
