The first question that comes to mind is what sort of shooting you're doing. Do you just want the flash off the hotshoe but still neatly within reach, or do you need to be able to move the camera freely around while the flash stays put (or vice versa)? If it's the latter, you are probably better going for wireless transmitters. If you are shooting relatively unmoving objects in a static setup, or you are putting the flash on some sort of oversized L bracket still mounted to the camera, there are cords available (OEM and third party) which give full P-TTL protocol connection between the camera's hotshoe and the flash unit if that's what you think you need.
If you go via the sync port, you are on your own - the sync port transmits only the 'fire' command, and you have to handle power settings yourself - either via guesswork, chimping, or an exposure meter that does flash.
Even if you had an original K-3, the problem with using the on-camera flash as the master controller is that sometimes the disposition of camera and flash as dictated by the scene may be such as not to reliably trigger the flash unit. IR remote triggers have a similar problem. Radio triggers do not suffer this issue.
