Anyone know which wires drive each door speaker or speakers on the big plugg I assume for the OEM radio non fosgste?

As I just want to depin it and pickup signal with a homemade bundle and pins I plan on making if possible, then run into a LC7I then to my amps without cutting the factory bundle for signal.

I've tried searching but I must be entering the wrong words, so please excuse me if its already been put up somewhere.

Thanks for any help.

 

Find the electrical maintenance manual for the car, it should have the colors labeled for the radio in there.
