Adriatic, your points are well taken. And if I planned to be moving many times, I most certainly would have used quality plugs for quicker assembly and disassembly. Molex connectors are fine for lights and accessories, but for track power and digital signals, I much prefer Anderson Power Poles over Molex. They seem to be easier to connect and the signal strength is better. Your mileage may vary. Plus you can buy them rated for 10amps and configure them to your particular needs. AFAIK, the original heavy duty Molex connectors we used have been out of production for some time and are scarce as hens teeth.But I digress, as I’m not planning on multiple moves and time is not of the essence.
