So My original set up was just a AM radio and stereo 8 track with proper harness.Converted to a AM/FM mono radio.In both set ups the rear speaker only plays with the Stereo 8 track.Both Radios only through front speaker ,even though there is a rear speaker spade on the 5 spade connector coming from the radio but not used by my harness set up.Can I just run a single wire from the rear speaker radio spade and tap into the rear purple speaker wire, and have the radio play through the rear speaker also.???Or just get a stereo harness thats meant for a red dot stereo radio?
