Buzzer & Chime Modules
The large black one in the lower L is a true
chime module used in '90-96 trucks. The smaller black one above it is a buzzer, and they're interchangeable (7 terminals) even though they perform differently.
The top center white one is probably from my '83 Custom. The green ones are newer. Note the lack of the 7th small terminal on the top L white buzzer. The top R black one is probably from an import (BMW maybe?).
