67 Dart Headlight Switch Demystified

This dimmer feature is often the one fault in otherwise fine headlight switches. Its too simple to just add a jumper bypassing the rheostat. Illumination will be full on bright as possible no matter where the knob is turned to. I didn't bother to use a multimeter and finger out which spade terminals or wires to link. My jumper goes straight down through that small hole in upper contact to center contact directly below it.
