Bad reverse light switch?

[Burke]

After some thorough research, I'm thinking that my reverse light switch here (https://www.ecstuning.com/b-genuine-volkswagen-audi-parts/back-up-light-switch/0b1941521b/?gclid=CjwKCAjwycfkBRAFEiwAnLX5IXyHvoyxVHVkT6siCNk-4DrBTZYvWSw5AoLsEBEQXC0bOPbv-og1_hoCBRcQAvD_BwE) may have gone bad. When I put the car in reverse, I no longer have reverse lights, backup camera, or parking sensors. I also ran a vag-com scan that returned the results below. Does anyone know where this part is located? Is it possible to get to from underneath? I'm planning to test the connector with a paperclip to see if that activates the reverse lights, and if so I'll replace the switch.
