Instrument Cluster Removal

you can try to bridge that gap but those traces are really thin. I'd go with a jumper wire from one end to another of that trace and solder it to the pin and pad. there is a bit more "meat" of copper there.
Any idea where that black wire runs to? It feeds that pin that the broken trace is connected to. The bulb on that is the high beam indicator and it also connects to the voltage controller.
