This board is normally a drop-in place board. Only problem is the holes for the screws are not big enough. You must bore them at a bigger diameter for the screws. After that, just make the board in place. The board is delivered with an other batterie wiring. You don't need it. Reconnect the original wiring at the same place as the original board, it works. Other problem is a lot of bounce. All my filters are at the max to not have bouncing problems. The programmation is a little different as the WAS board (you must hold the trigger to see the programmation of the board, not evident).
But this board is very fast and can see if the hoper is not feeding properly. Since I have this board, I've had no chops (due to the gun (barrel breaks)). The product is fine designed and the board box is beautiful.
Just another thing, in this box, you'll just have the board and a batterie wiring.
You don't have documents, you must dowload them on the lucky internet site.
I good board at all with a lot of parameters to programm. You can fine tune this board and it rocks
