Hi russ

I either mount the flash directly on the reciever or I use PC cords that came with the triggers. I had to cut the big jack ends of the trigger PC cords and did the same with some spare Vivitar PC cords. I then spliced the Vivitar jack onto the trigger PC cord. There are some hacks on Flickr to put a generic PC port into the hot shoe mount of Vivitar 285s. I would be tempted to go that route on the 283s if I where to start over again. I hope that helps.
