RE: Keeping connectors together?
Or you can cut em yourself out of plastic. Just cut a strip of PVC 3/8ths inch wide, drill it twice with a bit wide enough to slip the wires through and far enough apart for the slack of the connectors and cut from the side of the plastic on one side each hole. Slip the wire through the cutout, make the connection and pull out the strap. In essence, you are making homemade Earnst style connectors.
Oops, forgot this was in Tips n Techniques and not SPAD. You can make em out of coffee can lid plastic if you don't have a stack of PVC scrap hanging around.
