Mystery wire in headlight harness

@1969383S this is the harness that was in the car. I can’t say it’s original to the car, but it is an original harness. I’ll ohm out those two wires and make sure my thought is correct.

Good deal, you seem to be looking hard and paying attention. I figured as such based on the posts.

What exactly are you working on? 69 Dart? It is confusing based on the #1 post.
