What is this uncovered plug ?

Directly above the exhaust on my 2025 TRD pro , should I cover it ?

That's the rear AUX plug. It is unpowered. One of the wiring harnesses you should have gotten is to plug A into C which sends power to the rear. I believe it sends the 15A/AUX1, but you could rewire it if you want.

Bonkers the rest of mine have dummy plugs on them , I’ll check if one of my others fits and order a new one to keep it clean, thank you
