Syncing with PW's



So ever since I purchased my beloved 500c, I've been wanting to make use of that beautiful leaf shutter and sync some external flashes. 

I own 2 canon compatible flextt5's and pocketwizard said that in combination with their $30 (seesh) hasselblad dedicated cable I should be able to achieve what i want.

So after purchasing the cable and programming the triggers to basic mode as instructed... nothing. It just seems as though my 80mm lens isn't sending any signal through to my PW's.

Any one had experience with this or similar, suggestions would be greatly appreciated.
