What is this wiring bundle behind the headlight?

[jshatch]

I was changing my headlight bulb when I saw this bundle of wires and I would like to know what it is for. It's 6 wires all capped off.

Did your truck come with parking sensors? Possibly that’s what those are for

I do have the front and rear parking sensors.

That is a pretty HOT color of pink on the female plug!!!

Look like the wiring that you splice in to for snow plow lights.

Jimmy07 beat me to it, I was just looking thru the 2016 Upfitter Schematic.
I've got those same cut wires with heat shrink. No upfitter switches.
