The back up monitor has a speaker on it. We've never intended the audio to play through the Magnadyne. I supposed it could, but that's not what we shoot for. You just need to hook up the blue wire...to the back up wire (whatever color that may be on the Ford. I'll see if I can find out). Or find the reverse lights fuse and trace from there.
The blue wire, gets power in reverse. That is what powers the audio driver on the back up monitor.
