Review on 🔈 Efficient Pre-Wired APIELE Momentary Speaker Mounting for Industrial Electrical and Controls & Indicators by Brandon Wynen

Many reviews say that the schematic is wrong. Which is good because it's wrong. The schematic shows this in colors that don't match my connector, and also a connector that isn't the same as the one I have, but is commonly and usually reverse closed, like here (ignore the underscore, Amazon doesn't like spaces ). :___+C NO NC___-C means common which is your battery or ground for your horn depending on how you connect it. NO means normally open, which means you press the button to activate that wire. activated when no button is pressed + this is the power supply for the LED (that's all, just for the LED) - this is the ground for the LED (that's all, just for the LED) The connector I have, is more like that, and Common and NC are on the "reverse" switch (ignore the underscores): _______+NC NO C_______- I made a breadboard and here's a picture of how to wire it up if you'd like that the beep sounds when a button is pressed.
