Rear parking sensor not working

Hey y'all. So there are four rear parking sensors, two on the outside, and two on the inside near the license plate. After I installed my flush mount LED's, I noticed the inside right (when facing the license plate) sensor does not work. Troubleshooting, I swapped it with the inside left sensor, and it worked, so it's not the sensor.

I was about 100% positive I wouldn't hit the sensor or the wiring when I cut through the bumper installing the LED's. If I did, I would reckon the OUTSIDE right sensor wouldn't work...but it works just fine.

So, does anyone know if the wiring going to the outside sensors also contains wiring from the inside sensors, and maybe I nicked one wire when cutting? I traced the inside sensor wiring to a harness, but after that, it was hard to tell if the wiring then went on to the outside sensor.

Or is there anything other than wiring that would cause a certain sensor's LOCATION not to function?

I want to rule out everything before I take it to the dealership for warranty work, and hear the dreaded "you probably messed it up when you installed those LED's"...and also I'm too lazy to remove the entire bumper to troubleshoot further

Figured I'd try my Tundra brothers and sisters first...

Thoughts are appreciated!!
