Tyto-01 Radio Install: 2004 IS 300 Base Sedan

Hi Guys:

I'm using the Tyto-01 wiring harness to install a new radio in my wife's Lexus. Instructions say the Blue/White wire goes to the AMP.

I don't understand how/where I connect it. Help would be greatly appreciated as I've done numerous "searches".

there is a wire on the back of the radio that is just a turnon/power wire that goes to the factory amp, so that the amp is only on when the radio is on. You connect the harness to that for the same reason
