1990 4Runner Alarm

Just bought a used 1990 4Runner with what looks like a Toyota alarm system. The manual does not describe how it works at all. Any help is appreciated. The ststus light is flashing 2 flashes then a short pause then repeats. Also getting in and starting the car causes a loud relay cycling under the dash with no horn or siren.

i have a 90 4runner i turn the key the light goes off not sure what is the noise you have but somethings wrong that's not normal. sorry couldn't be more help
