Anyone have head unit wiring codes?

[Vroom]

My friend and I are making the tape signal become a direct line-input.

I need to know what each wire is for and what color it is. I'm sure there's a diagram somewhere that has them numbered and then tells what each one is for.

I searched and found one, but it was for the amp wiring.

Thanks

Here's schematics for the jbl in 1996, I'm sure they are very similar to 97:
