chassis using the mounting holes that held
the old alarm.
2. Mount the alarm in the flange (Figure 3).
a. Remove the plastic nut from the alarm.
b. Insert the alarm through the flange.
c. Secure the alarm to the flange with the
plastic nut.
3. Use a provided wire tie to secure the wires
from the alarm to the body of the alarm as

following the same path as the old harness.
Connect the red wire to J1-16, and the black
wire to J1-12. Polarity is important (see
