You're going to have to show the PCB and where the traces go. Depending on the pin, it changes how and where you have to jump the wires.
Here is what the PCB looks like

I am following the traces, for example on the [ key, the right hole connects to the bottom of the corresponding diode. For the left hole of the [ key I am not sure, it looks like it doesn't connect to anything.
Other keys like the ] key, the left hole has a visible trace.
