Help identify an underdash wire

[martincj]

I was adjusting my brake light switch under the dash when I noticed a black wire with an orange stripe hanging down unplugged. I looked for its mate but I cant seem to find its home, one end is unplugged, the other end is plugged into the white plastic smaller distribution box that faces the floor board?

Not quite sure what the pink wire is either, but the connectors don't match.

In the fuse block, center right there is a silver 30A circuit breaker marked PWR ACCY. To the lower right is a BAT opening, that is where the wire/connector goes.

Not sure what the pink wire is for, but that color is typically used for ignition switched power.

Thank you, I found that the wire provides power to the power door locks. As soon as the plug made contact it made a loud thud sound, so I know why the previous owner must have disconnected it
