Probably a dumb question

I am researching what this wire in the bed is for, it appears to run down and connect to the body harness and is a red wire. I've only had this truck less than 2 years now and still discovering things. 2013 sport.

Yeep, it's the on off switch for the factory bedlights
I don't believe the trucks came with factory bed lights til the '16 or '17 model years, and don't think prior years BCM supported the factory bed lights. Also the factory bed lights would be in that back corner of the bed.

I would trace the wires down below the bed, it could have been a disconnect for a third brake light on a topper.

Looks just like the feeder wiring for the topper on my 2014 Ram.

Since it is there. Easy feed for LED bed lights.

Great step by step How-To video on youtube.

Appreciate the info, I dont have a topper so I'll just tuck it away somewhere with some zip ties so it's not just open to the elements like it has been

Check and see if you are getting voltage. Full time or with just lights on.
