The nut/bolt protruding from the motor is the positive lead. Use 4-gauge (sometimes called "No. 4" or "battery") cable with appropriate ring connector. Unit is grounded when mounted to the vehicle, assuming it's mounted to a metal surface, which is mounted to a metal surface, etc. Fuse appropriately.

If testing with a power source other than a vehicle (battery charger or such), attach the positive lead to the aforementioned nut/bolt & secure the negative lead to the siren's base. Ensure the siren is secure before applying power, and keep fingers away from the rotor.
