I'm prepping to install a new head unit and potentially remove the security system and found a piezo alerting buzzer under the hood. I have absolutely no idea what this is for. I feel like there should be some of prize for solving this mystery.
Piezo alerting buzzer?

That’s for the factory RS3000 alarm system. It makes a chirping sound almost identical to the ones Toyota’s and Lexus’ make to this day. I’ve had a bunch of 80’s with the factory alarm and all of them stopped working with the exception of one rig that I have with less than 40k miles

Ah! I do have a non-oem fob to lock/unlock, so it seems this is an aftermarket door lock system then? I actually like the remote lock/unlock, but don't need the alarm functionality. I am going more and more nervous about the wiring i'm going to find.

This is factory? A radioshack buzzer just hanging by the master cylinder? Un-possible!
Its been replaced. I replaced mine. I think the Radio Shack one is mentioned somewhere here on MUD as a replacement. The OEM buzzer is slightly better installed but not much.
My factory one was wrapped with foam tape and attached to another wire under the master cylinder. Pulled off the foam tape, replaced with new piezo, ziptied back to the old spot and now I've got a working 'beep' when I lock or unlock.
