Delco radio external speaker wiring???

I'm trying to install a replacement radio and a Delco model 30015807 radio was removed by my grandson and he lost the Delco radio's wiring plug after he cut the wires off and connected the 13 wires to the new replacement radio and the new radio did not operate correctly! I tested the new radio on my test bench as still a ok, but I do not know the color code of the correct wiring of the Delco? (for example I need to know the color diagram of the orginal speakers wires, and power input wiring of the existing 13 or so wires? Where can I find such? It's too late for a simple cross adapter because he lost the orginal Delco radio mating plug after he cut off the wires! Does anyone know the color code of the Delco model 30015807 external wiring?

Thanks

we need more info to help, like what car.

A Haynes manual should give the schematics for your specific vehicle. It did for my truck.

The car is a 1995 GEO, but I don't know the style model!
I'll contact my Grandson and get the car's info and get back to the forum!!

Thanks
