Im trying to install a stock radio I got on Ebay on my Dart but cant figure out the wiring. To make matters worse the wiring is kinda hacked up in the dash. The radio comes with 3 plugs. One plug is made up of a red and an orange wire the other is a single green wire that makes a plug and finally theres a black wire. In the dash theres a socket that I am pretty sure is where the orange and red plug into but I don't know what to do with the other wires???Any help would be greatly appreciated.
