I have a device with multiple input/ output wires, maybe 8 total. I would like to know the best low cost connectors that will look good. For example, if I just have one wire, I can make a nice clean connection with a soldered barrel connector and heatshrink tube over the black cable and barrel connector. But when I connect more than one barrel connector, the heatshrink is unable to neatly cover more than one barrel connector. Using electrical tape doesn't look good either. Any tips?Ideally I'd like one connector for every wire and a way to make it nice and neat looking.I don't know much about connectors and cleaning things up.
