does anyone have the pinout diagram for the Echo head Unit. It is the stantard Stereo set that comes with the Echo. I am trying to put 2 rear speakers.
The headunit should only have 4 spare wires left or 5 (if it has no electric antenna used). So there should be by right two pairs of same colour wires. The striped ones are positive. You can work out which channel they are by fiddling with the settings on the headunit.
