Melted Headlight Connector Replacement Found

If anyone wonders why this service part is available as listed for those Jeep applications.... fog lamps.
Ford had the very same issue with several year models of Mustangs, T-birds, Escorts, everything with OEM fog lamps. Those would melt headlight switch, multifunction/dimmer switch in the steering column, and the wiring between the two switches.
This connector meltdown isn't nearly so common in other vehicles ( like our a-bodies ) but yeah I've seen it before. Never knew exact cause. Something other than OEM bulb type is my guess.
