FY -1604b(4) infrared emitter not working

Hey everyone ! I recently bought an infrared emitter (the FY -1604b(4)) and a JST-PH 2mm cable to use in my project, but when I inserted the female JST-PH cable in the male port of the infrared emitter board I realized the cable's black cable was next to the 12v label on the board and the red one was next to ground label, I figured this was probably some sort of coloring issue from the manufacturer and tried the product with my 12.6v battery, I hid the light level sensor and pointed it at a camera I have without an infrared filter (that is sensible up to 840nm) and saw that it didn't work, I tried uncovering it and it still didn't work, I even tried with my tv remote which actually showed up on my camera's display. I tried swapping the cable and still nothing and even tried looking with my multimeter in resistance & continuous mode to see if it was properly wired and the multimeter displayed "0l" meaning there was an issue. I honestly feel like there is probably an issue with the alimentation port or the light level sensor but I'm not sure and I hope not honestly, but I was wondering if anybody knew if I was missing something or something was wrong and I just didn't realize? (here is a video of someone utilizing the product and showing how it works : https://youtu.be/HbjDPwX839M) (the picture is the infrared emitter & the cable) I'm sorry if this isn't particularly related to arduino but I figured I could probably get some help.
