Amp Problem, need help
 

I have a 2001 monte carlo ss and the amp went bad. I found a stock amp online and bought it but it is off a 2002 monte carlo. When i tried to switch my old amp with the 2002 amp, i realized the harness for the black and orange wires does not fit into the newer amp. Is it possible to just buy a harness for the 2002 amp from somewhere?

The amps should be the same with same plugs and hook-ups. Post pics and maybe I could help...
