2000 PA Ultra Radio Wiring

[Five]

I cannot afford the wiring harness I have seen in previous posts. I am wiring my aftermarket radio to my 2000 park ave ultra hard wired. Does anyone have a wiring diagram for the radio wires or know what each of the 21 wires goes to?? Any help would be appreciated. I know I could do a trial and error but I just want to try and save some time. Thanks for your help.

Thank you for the link, it was very useful. My car has 9 speakers, steering wheel controls and 21/32 wires. I think I will just trial and error from here. Thank you.

I think if you look on the Crutchfield site you could find the diagram.
