My radio finally went in my 2004 Cayenne S.

I decided to go after market and bypass the MOST amplifier.

I'm running speaker leads from the amplifier to the new head unit and I can't figure out which wires are which to tap into in the BOSE amplifier wiring harness.

Does anyone know the color codes for FL, FR, RL, and RR going into the Bose amplifier?

I have Bose, Nav, and CD Changer... all I need now is which wire is which!
