They will work in Manual but might be too vintage for updating to their TTL converter compliance, they have a notice concerning this compatibility just check your serial number with this list or shoot them an e-mail with the strobes serial number, if you don't care about TTL, many here don't, then they are ready to go, the Subal typically comes with Nikonos type connectors, so you might have to get sync cords if yours is from an Ikelite housing.
As a side notes, current battery pack for the DS160/161 are the same, but are now NiMH, so if you get new battery packs, check to make sure your current charger can handle them.
