Top right cavity is damaged. Off the top of my head that might be for wire L1.
Get a replacement connector.
If that is L1 with the AMP Fast-on 1/4" spade terminal, replace with a Chrysler or Packard 58 for 14 or 16 gage wire.
Sorry but that's what is needed so it will have a good connection and won'tslip out the back when the connector gets installed onto the switch.
If you were desprate I'd tell you could cheat it if you added a headlight relay harness. But its all on the bench so do it right.
Headlight relay harness is a good idea anyway, but that can be a plug and play in the engine bay. The headlight circuit is the one really weak circuit, especially with higher watt lamps than the car came with.
