I was getting a buzzing from my control box the last time I was out untill I switched it to neutral. Is that the overheat alarm? I just put the control box in and wasn't sure if thats where the alarm is, is there a temp gauge in there.

I have a 1990 v-200 2.4L Merc. My understanding was the alarm is either a add on under the dash or someone told me that the motor has a built in alarm but I dont know where that would be, or if you could hear it if it was in the motor. Why would the control box be buzzing. thx for any help
