I HAVE NOTHING BUT HEADLIGHTS "update '

THE HEADLIGHT SWITCH in most Mopars has TWO separate power supplies. One is NOT fused and comes from the black wire off the ammeter from the "welded splice." This supplies HEADLIGHTS ONLY

the second power source comes off a fuse and supplies the tail/ park lamps, the dimmer controlleded dash lights.

IF YOU do not have a factory service manual (and I don't know what you are working on) go to MyMopar and download the closest one. You may have to settle for Plymouth vs Dodge and vise versa
