Hello, I want to modify the SC-17 with an extension cord with plugs for long distances and just a couple of short curles for bracket mounted flash. Has anyone of you ever done that and can tell me: How many pins do my plugs need = how many wires are inside such a flash cable? Any further help or recommendations? TIA sImOn, Vienna, Austria PS.: I know that there is a company in the US making such modification, but I life in Europe...
