Basic Question About 1970 Key Buzzer
I am finishing up my interior refresh on my 70. I changed the courtesy light/alarm switch at the front of the drives door. Now that I have the steering column back in I've been able to put power through the car, and test out the systems I repaired.
So my question is: what is the normal operation of the key buzzer?
I have seen a million threads on how to disable it, but I want to know that it is working correctly before I make any decision on unplugging it. Right now when I open the driver door I don't get a courtesy light (which I need to fix). If I put the key in with the door open my horn relay starts squealing. Once I turn the key forward 2 clicks that horrible noise stops. Also with the key in the original position if I close the door the squealing stops. Is this the how the buzzer is supposed to operate? Or have I got another issue to fix?

Operation... it will sound when the key is in the ignition, in the off postion and the door is open. It sounds to me that it is operating correctly.
If you want to disable it, the easiest thing to do is to just disconnect the wire from the buzzer from under the buzzer itself under the driver side wheel well. Should be a tongue connection. Tape it up good so the end of the wire doesnt risk touching anything. You can easily connect it back when you want to.

In my 69, the horn still works when I disconnect the buzzer. I would think it is the same for the 70... but who knows lol

You know what... I'm really not sure. It may be the case that the buzzer under the driver side wheel well is also the horn relay, but I would think that if you disconnect the wire from it to disable the buzzer, that the horn would not work.

For 1971 (at least) the horn relay IS the key switch buzzer. It is powered when: then engine is not running; the ignition key is fully inserted into the ignition switch; the driver's door is opened.
The 1970, 1971, and 1972 cars are all very similar...and I would be surprised if that key warning system was different during those years.
