I need help for my Fai-300V alarm system

I install the fai-300v in my  MR2. Since I don't really know about the C3 connector. Which is the black wire connect to (pager Tr +) . What is this wire mean and How can I find it? Also when I hook up the alarm. The door lock and unlock is Ok. But the siren doesn't chirp. But when I enter to the program feature mode. The siren will chrip. ALso the alarm Led will be flash all the time. Even I disarm or arm the alarm. Also the trunk lock button also doesn't work. Do I need to programming the alarm or not???So Is anyone know why this so many problem happen for this alarm?????

I have the same problems with my alarm. I also have a fai300

The pager wire, you don't need since the fai300  doesn't come with a pager.
