Can the bed lights be wired into the 2015+ OEM bed lights so it works with button too?Updated 10 months ago
Yes they certainly can! You can locate the wires for tapping under the rear passenger door kick panel.
For your ground wire (black) splice the black/yellow as seen below in this BCM wiring guide.
for 2015-2017 trucks please use the violet wire for power.
for 2018+ model trucks please use the white/green wire.
