The sealed beam headlights that were used for about 40 years all had a standardized connector that crossed makes for all cars and trucks. Even the 4-headlight vehicles that started in 1958 used the same 3 pin connector for the high/low beam lights. It doesn't matter what year or make of vehicle you use as a donor- - - -they will all fit and work the same way. BTW- - - -the center pin of the three IS NOT the ground! To determine which headlight pins are used for each beam, I'd suggest using a battery and some jumper leads on a headlight.
