Does anyone know where I can find a headlight switch harness or just the switch connector for a 69 Barracuda?
Yes - same as in the Jeeps. This are the ones I useThe harness connector for the headlight switch is the same in many Jeeps. Just search it for Jeep CJ. Jeep owners would melt them down by adding lights incorrectly. If the connector in your car melted, you need to hunt for why this happened. If you added frog lights without a relay and separate/dedicated power source, there is your cause.
