Was about to vacuum the drivers side floor when I noticed this wire hanging there, not plugged in. Purchased the vehicle used about a year ago and haven't had any issues. Wondering if anyone can shed some light on what this wire is. It's two wires factory taped and terminated to the black plug. One black the other yellow/violet(ish). Any help will put my mind at ease. Thanks everyone.

That’s for footwell lights. They come standard in the higher trim level. I actually used the wiring to feed my lights for my truck steps instead of taping the cargo lights. It works great because they’re on with a door open or when you unlock the truck and they fade on and off.

Yep. Footwell lights. My 2017 Ram 1500 quad cab 4x4 V6 was the same. I bought a set of mopar footwell lights online for cheap to have something to plug'em into. LOL.

You have to poke around a little bit to find the passenger side wire/connector, but she's there. The footwell lights are hard to live without once you have them in your Ram. FWIW, my 2019 Ram 1500 SLT classic, CC, 4x4 came with them.

I believe if you look around a bit more on the drivers side, you will find the wiring for the trailer brake controller, if you don't have one installed
