Thanks for that. I was thinking along the lines of what you said, using heat shrink, ie: heat shrinking each individual wire then one larger piece of heat shrink over the whole lot. I think heat shrink is brilliant stuff but in my experience of using heat shrink it doesn't necessarily make wires water tight. I have found in the past that water/moisture can still find its way between the heat shrink and wires due to capillary action. It could all end up more trouble than its worth. Heat shrink doesn't actually bond itself to the cable, where as a moulded connector does.
So, back to my original question, "Hi, does anyone know where I can get Julet 9 pin connectors only without the cable?"
