Joe, it was just a matter of space. Four wires and three pins with a very tight fit - that's the only reason I couldn't get it alone. The Janome salesman who doesn't care for vintage told me that two wires couldn't fit on one pin. Luckily, I had a printout of the Singer schematics with me. The retired repairman who only works part time wouldn't have had an issue.
I just saw the retired one at a store. I almost asked him if he wanted the machine. He could fix it - he has told me how. I just need it out of here now.
Mark, there's no market for a parts machine around here.
