Hello I'm in the middle of installing 2 subs and an aftermarket touch screen in my 2000 Gs400. Behing my factory unit there is 4 plugs. Orange, 2 greys, and a white. On my factory amp there is also 4 plugs orange, white etc....
I have everything layed out and ready to be connected. But before I start slicing, I need to know exactly what each plug contains.
I am bypassing the amp in my trunk, so I need to know which plug is the output and leads toward my speakers, from the stock amp, so I can directly connect my factory speakers to the after market unit.
In the dash I need to know..
Is there a constant 12v or do I have run one from the ignition harness?
Is there a remote wire behind the dash?
Ground wire?
And power antenna..
