I used a Y cable with much success on my old 132c. I had it made at http://www.paramountcords.com
Basically it works like this: The long end goes to a mini plug for a flash wizard to trigger the strobe, one end of the y is a pc socket to go to the hassy lens and the other end of the Y is a micro plug to go to the 132c back. It worked great. I used it on a Cambo wide ds and a Hassy before I got my Contax.
