I am using a PSU to light some cathode tubes. I need to extend the wires about 6". Do my extentsions need to be exaclty the same length? Say, if the wires are an inch different, would that cause problems?

Also (seperate, but related project). I have a device that plugs into the wall (120v AC). I want to splice the wire and put a toggle switch in. Does it matter which wire I splice?

I want to extend either the molex connection (PSU to Molex) or the Molex to inverter wire.
