Where do these wires go?

Can someone please tell me where the top two wires on the far right column of the bulkhead connector go? Someone replaced them with what looks like a 2 wire lamp cord. I assume they go to the reverse lights or neutral safety. I traced them under the car and what is left of the wire is cut, mangled and twisted together.

It's a 1971 Dart Swinger. Originally a 318/904 car.
