I'm confused. I have a 1974, it did not have any lighting package. I've reconnected the seat belt interlock and the lamp comes on when the conditions are met. However, there is no buzzer. I've tried various combinations of the key in the ignition/door closed/open/lights on/off all without any sort of buzz.
I tried replacing the relay, I have 3 different relays. The 3 prong that came in the car, a replacement 3 prong of that, and 4 prong. All of them fit into the block, the horn functions, but again no buzz. Am I missing something? Is there another piece like an actual buzzer somewhere?
