Agreed, the two pin is the main suspect..... or the wiring after the two pin, possibly. As I said, it's hard to screw up connector wiring unless splices have been done. I.E. connector eliminated and wires butt spliced. You never know what previous owners have done.

At/after the radiator baffle connector, the light green wire is four-ganged to all headlights. The tan wire is routed to driver outside headlight, then to the passenger outside headlight. Incorrect colors may have been used, so be aware of that.

If you get stuck, post some good well lit pics of that connector and the wiring.
