That will work. It's so you don't pull your power from whatever accessory line you use. Otherwise you can pop fuses. You connect your accessory to the relay switch side. Run power and ground from good sources. Either at the fuse block or battery. They have easy to add fuses that will give you a fused power source. Not the best. But fine for what you're doing.

Run this to your relay. Then use the output of your relay for switched power
There are lots of other ways to do this. This is what I feel is the right way
I'm confused about why you've twisted the red and yellow together (rather than yellow to black), as he used a simple two-wire piezo in the video... Regardless, as you've got it, do you get a buzz with the engine off, headlights on, and black grounded (to the engine block or the AC fuse, as you've got it)?
Would you describe how you wired the buzzer to test it (what you connected each wire to)? I think you're super close to getting this working -- if you haven't got it already.
Edit: For you or others, I'd recommend implementing a fuse tap to safeguard the addition you're making to your electrical system. You could use the same amp rating of the fuse you're tapping.
