Wether or not the Shocker is a vertical feed (preferred for ease of fitting) or standard feed, the fitting is the same for either marker. If you are asking how to get the Shocker to "talk" to the warpfeed (react with each trigger pull) then that is a whole different thing you "should" be able to take the signal from the hopper control on the Shocker board (not totally sure thats why I have said "should") but other than that you would have to add another switch in the grip (like the intellifeed frame from AGD) full instructions to do it that way can be found on the AGD website but you would have to do some adapting to the Shocker frame.
