Year One Dash Harness

Take a look at the wiring diagram for your Demon and compare it to a Dart or Valiant of the same year. I used a Coronet wiring harness in a 69 Charger. The wire colors were the same and I just swapped out the round connector for the blade style connector from a junk harness. I didin't even have to cut a wire, the plug ends just slid out of the connectors....Worth a shot.
