Wires on the rear wall that aren’t connected to anything

[ChristianR]

I removed the rubber/carpet mat that is on the rear wall of my ‘15 Sierra and seen 4 plugs hanging to the left of the wall that were not connected to anything nor was there anything near that they could be connected to. I thought it mightve been the bose plugs but i dont have a bose edition. Please help

The logical thing to think is that the wires are for options you do not have.

 

So think about what you your truck is equipped with and think about what else is offered. Like maybe a sliding rear window, rear defrost or anything else rear seat related.

Parking sensor module lives there too.

These are the wires like suggested above. Rear sliding window, Bose system, ETC. Its easier to build and install a wiring harness for everything and just not use the leads when not needed. That way there is no need for several different wiring harnesses for the trucks and if the wrong one gets selected or installed on the assembly line they won't have to go back and correct it.
