I want to put two electronic turnout switches on each side of my 4 ft by 8 ft layout and have all the switches on my control panel under the front of the table. The wiring instructions says plug this into that but they only give you about a foot of wire between the plugs. I need over 4 ft. Do I have to cut the wire between the plugs and soder longer wires in to reach the panel or can I buy extensions?
