Are all 3 of the wires coming down from the top of your picture black? It's hard to tell if they're actually black, or if they're just dirty.
If they're all black, then wrap a piece of tape around each one and write the corresponding color on it. Or use colored zip-ties. Or tie a piece string around each one - 1 knot = yellow, 2 knots = pink, etc. There are plenty of ways you could mark the wires so you can match them up to the other side of the connector.

In your picture, they're still plugged together. Write down on a piece of paper which colors match up when they're plugged together, then cut the broken plug off and wire the matching pairs together.
