1993 Plymouth Acclaim

I have a 1993 Plymouth Acclaim sedan - I have tail lights but no headlights. A few months ago, the front left side harness connector came apart and I had no power. I checked all harness connections in the front for any loose connections to the lights but can't see anything disconnected. Where else do I look? What about the fuse that belongs to the headlights? Which one? Unfortunately, don't have auto shop manual for this. Would really appreciate help. Can't drive anywhere at night.
