Possible to fix wiring on headlights?

[Big J]

hello,
is it possible to fix the wiring on the headlights plug in? on of the wires broke off of the little clip.

also, on my set of under car glow, there is a wire that was 2 rounded tips on them like wire connectors and has a hole in the center. like you are supposed to put a screw through the center.. it goes from the chip that mounts on the under side of the roof then it should go to the little white harness that plugs in..
any ideas here?

thanks!

i can get pics if it helps.. i am just lost as to how to get the lights to work? my other car which is also a gen 1, has a different setup for lights.
