The "plug and pay" lights have been around since the 1970's by all manufacturers. They were designed for trucking fleets. I have more experience with trailer harnesses than I ever wanted. A volt ohm meter is a very useful item in combination with a good manual. Corrosion, vibration, and excessive heat are the chief causes of failure in electrical systems. The "magic" of high mileage cars is preventive maintenance and being "smarter than the metal" by knowing the nature of materials.
