Remove the 4 screws holding the trigger cover together and seperate the 2 halfs. The trigger is installed in the left half, slide the end of the cable into the socket on the trigger. Slip the trigger onto the post located just above trigger cut out. About 2 inches from end of cable there is a rectangler shaped box around the cable, this box fits into a holder about the same sizealong bottom of trigger cover and the rest of the cable snaps into 2 cutouts between box and end of cover. once this is done reassemble cover to shaft making sure that tabs on end of cover fit into cutouts on moter housing.
