I have a 2000 Lexus ES 300 that somebody cut the radio harness on the head unit. It is a pioneer radio and I need the wiring colors for the wires going from the amp, to the blue plug in the back of the radio.

I can can only find the Nakamichi schematic and the colors don’t match. I have a new harness so I need to know what each wire is for that go into the deck

Please, been looking too long! I can take some pictures If necessary.
