Step 3: Make the connections to the switch pads
You could solder 12 wires directly onto each side of the six switches and all would be fine. However, this would have to be done on the tracks-side of the PCB and the buttons could then not be used. This would stop the remote control from being used in its original way.
I chose to work on the other side of the PCB and find suitable connecting points to gain access to the six connections I needed. There were suitable links and holes already in the PCB, so I did not have to do any drilling.
I had some very fine enamelled wire which helped some of the connections, otherwise I just used ordinary insulated connecting wire.
