Rear Speaker set with cable

[sharkbyte]

very interested - however, I have replaced my 220 with a Pioneer double DIN head unit. How does the plug work? Is it in the harness or directly to the head unit? From your pictures it seems like it should connect to the harness which goes to head unit. I assume as rear speakers?

Thanks!
