Hello board,

I have a 2002 Lexus GS 430 with nav and the Mark Levinson surround system and having a hard time finding a wire diagram for the amp or the headunit. I need this diagram to figure out whether or not there is an amp turn on wire or a mute wire in order to install a Parrot hands-free system. Can I use a DMM somehow? Does anyone know where I can get software for audio wiring info for any make and model?

Thanks

On Toyota and Lexus the mute wire is usually Pin 7 on the 20 Pin Plug. I usually test for power and ground to get my barring on the pin locations, then count out to 7 from Pin 1 which tests as battery. Which is Blue / YELLOW according to the above post. Pin 11 is directly below pin 1 which will test as an accessory, so make sure you are testing battery and accessory correctly. This way you end up at pin 7 not pin 17.
