I’ve embarked on the long journey to fix the wiring that a rat (or more than one) has chewed up on my car. I managed to get the pins out if this plug, but how do I replace them? I have no idea what size they are or who manufactures them. The are marked H1 on the metal and above the H1 there is a triangle symbol. The plug is 11156 and it’s one of the plugs that goes into the headlamp.
