Step 2 

Attached the buzzer and the 9 volt batter holder using the three screws. You may need to be somewhat creative to get the parts to fit on there, especially if you decide to use the larger buzzer. Keep in mind that if absolutely necessary you do not need to include the battery holder on the front side, it could easily be placed on the back.

Step 3

Secure the black wire from the buzzer to the base of the mouse trap using a piece of tape. You want to ensure the very best connection so I would place the exposed wire end underneath the part of the spring that is strongest.

Step 4

I like to add some tin foil to improve the connection. Though it appears to be unnecessary, we have found that without it that sometimes the wire end moves and the alarm will not go off as expected. I recommend you use the tin foil . Slide the tin foil under the exposed wire and the fold over the top to ensure the best connection.

Step 5

Secure the black end of the snap connector to the mouse trap arm. I like to secure it under the spring so it will not move. You could also secure it with electrical tape.

Step 9

At this point you will attach a fishing line or black thread to the card stock (pictured above, but it is very difficult to see) and the line will act as a trip wire. To make this easier or more difficult play around with how far you insert the card stock into the trap.
