Hi what’s this black thing at the front headlight . Connected to black wires with spade terminal. It has no markings , just a small square plastic with 2 female spade connectors sticking out of the too located behind left side headlights. I have 83 320i
Thanks in advanced.

Do you have a picture or part number? Pretty hard to identify without.
