I cant seem to find this anywhere. I cant get the head to work right without it. I have the DATA computer but it doesnt seem to help with timing. I have plenty of timers but no cord. From what I understand it seems to be a 6pin cable on one side and a standard 2 prong household plug on the other end. If anyone can help me find one of the cables it would be extremely helpful. My enlarger head is useless without it.
