After replacing a melted headlight connector, make sure it doesn’t happen again by installing a ceramic headlight wiring harness. The harness connectors are build from ceramic so they won’t melt. Simply plug one end into the headlight bas and the other end into the new pigtail. That moves the pigtail away from the heat and prevents it from melting.
