The 9v battery hidden camera trick people keep wiring backwards

I keep seeing builds on here where folks wire their 9v to a camera module with red to red black to black but the terminals on a standard snap connector are reversed compared to most mini boards. It fried two of my modules before I checked with a multimeter last Saturday. Why does everybody assume the snap connector matches the board colors without testing first?

Is it just me or does this same backwards assumption happen with like everything in life? I swear people see red and black wires and immediately think they can just match them up without a second thought, like when I tried plugging in my new weed trimmer battery the same way and it sparked like crazy. Always check first, right?

Did you at least get a cool smoke show out of it?

Lost three modules myself to that same trap before I finally broke down and bought a multimeter.
