I need help finding something to fire my studio flashes

[Theantiquetiger]

I have had these older studio flashes for a couple years and have just been using them as a slave flash. I am trying to figure out what do I need to get to make them sync with my camera.

Any idea?

The sync cords are about 3 feet (1 meter) long, and the ends look like this (three prong goes in the body of the flash

There is another 12 foot cord (4 meters) with ends that look like this

and here is the back of the flash

Do you have the 6V PX28 or 544 battery installed?

Flash Zebra should have what you want. I've dealt with them several times and they're very reliable.

Not sure what you are asking, these work with out the battery as slaves, I want to sync them using the cords shown. I need something (radio controlled?) to fire the flashes

I have the cords, just need the controller

Do you mean a trigger?

Yes, I am guessing something like this:

2 Sets YONGNUO RF 603 Radio Flash Trigger C1 for Canon 450D 500D 550D 600D 1000D | eBay

BTW, what is the battery for, the sync power?
