If you get radio triggers (some as cheap as $20 for a pair) you can put one transmitter on your camera and each strobe gets a receiver. The type of cable you will need depends on the model of trigger and strobe as far as which ports they have. The PC Sync connector is/was common, but a lot of things now use 3.5mm (think headphones) connectors. Annoyingly, Canon cameras use 2.5mm (E3, as they refer to it) or their proprietary N3 connectors (neither of which is very commonly used elsewhere). However, if you're using the hot shoe as the triggering point then that isn't necessarily an issue.

Edit: In light of your added information, it sounds like you have Canon cameras and studio strobes that have a PC sync port. A cheap option would be this which will let you trigger two strobes. I have these and the only downsides are that the cables don't attach very securely so you want to tape them and (reportedly) they don't fire 100% of the time (I haven't experienced this, but I'm not the heaviest of users). The transmitter just sits in the hotshoe.

Also, your cable release port (left side, under a rubber cover flap, probably a 2.5mm port) probably works as a flash trigger as well. I don't know if I've seen this documented anywhere, but in setting up a remote camera using pocket wizards I discovered that this will work both ways (I have a 70d).
