Step 3 

Remove the single bolt holding the front roller on the trailer and remove the roller. Once roller is removed, replace it with the latch. Tighten the bolt snug, but not fully tight yet. Keep slightly loose so the latch can move just a little.

Here is a good visual if you have a double roller bow stop. In this version, simply remove the top roller, install the latch in place of the top roller and adjust the winch arm to line up the bow eye with the latching system. Another option is to remove the double bow stop completely and install the latch directly to the winch post.
