It's hard to say from your picture. Apple uses a black solder mask which is very low contrast so its hard to see. The connection is probably not that far away. Clean up the mess with IPA and then put a drop or two on the circuit board. It will act as a lens and you may see (under magnification) where the traces are and where they go. Then it's just a question of making a jumper or extending the wires if necessary.
