New throttle con*****, buzzer problems

I have changed throttle control from 703 to a new 704.

The buzzer donīt sounds, in model 704, as i used to do when I used model 703.

I have also mounted a adapter for ground cable for gauge.

Whatīs wrong.

The 704 control box does not have a buzzer in it, the 704 requires a 704-82570-08-00 key switch panel which has the buzzer in it.
