Err, that wont work mac.
You cannot use a PW to wirelessly trigger a 360fgz. The Pentax Wireless and PW are not the same thing and are not interchangable. PW uses radio signals, Pentax Wireless uses preflashes. If you have a PW as a sender (on your camera) then you need a second PW as the receiver (connected to your flash).
If you want to trigger a 360fgz using a pocket wizard, then, since it doesnt have a sync port on it, you need to get one of those hot shoes with pc sync port in them, then you need a second PW and connect that to the hot shoe pc sync and set the two PWs on the same channel.
here is an example of such a product, there are many different ones available.
you connect the cable form your second PW into the pc sync port on that device and put your flash in the hotshoe.
When using it in this mode, of course you will only get manual flash.
If you want to trigger a 360fgz with a k100d and get pentax p-ttl then you need a second 360fgz mounted on your camera to trigger the remote 360fgz.
Ask away if that doesnt clear it up
