I'd like to know as well. Noticed the same bundle of wires while hooking lights to my upfitters and wondered what they were for.

If u look at my picture above , there's about 15-20 wires, I swear they look like speaker lead, but not sure, the up fitter wires are only four and they are higher up almost close to the amp, anybody?
