RUNNING LIGHT INSTALLATION
Unscrew the two front sun visors and sun visor supports, put aside. Pull out the two retaining clips that hold the headliner to the roof, put aside. Unscrew the two front windshield pillar caps, put aside. Pull down the top of the rubber door seal. Pull down the front of the headliner inside your vehicle. Unbolt factory roof lights from vehicle. Set aside the factory nuts for later use. Unplug the factory lights. Plug in new Atomic LED lights (if strobe option is desired, see running/strobe light installation). Place new Atomic LED lights on roof in factory holes. Use the factory nuts, tighten. Reinstall headliner. Replace the front two windshield pillar caps, two roof retaining clips, sun visors and sun visor supports.
RUNNING/STROBE LIGHT INSTALLATION
A LED flasher is included for the strobe option. We use an Atomic Flasher made by Whelen. If the truck is equipped with upfitter switches, we recommend using one of these, if not use your own switch and connect the LED flasher. Unscrew the two front sun visors and sun visor supports, put aside. Pull out the two retaining clips that hold the headliner to the roof, put aside. Unscrew the two front windshield pillar caps, put aside. Pull down the top of the rubber door seal. Pull down the front of the headliner inside vehicle, unbolt factory roof lights from vehicle, set aside the factory nuts for later use. Unplug factory lights. Place new Atomic LED light on roof in factory holes. Use the factory nuts from earlier, tighten.Plug in new Atomic LED light to the factory plug. Run wires from LED flasher up to each white wire on the new Atomic LED light. Then reinstall headliner Replace the front two windshield pillar caps, two roof retaining clips, sun visor and sun visor supports. To hook up the flasher: run 12v(+) power from a switch to the 12v pin on the flasher, run a ground wire to the ground pin(-). Hook output #1 to light #1, output #2 to light #2 , output #3 to light #3, output #4 to light #4 and output #5 to light #5. You will need to cut the pos (+) wire on your factory harness before the first light. Run the truck side of the cut wire to the running light in the pin on the flasher, so when your lights are on and you turn on your strobes, the roof running lights turn off. See diagram. To change the flash patterns on the flasher, with the flasher activated: To cycle forward to the next pattern apply +12VDC to the S/L pin for more than one second and release.
Note: If the light strobes and the roof parking lights do not work, some 2007 and earlier models may require the (+) and the (-) wires to be reversed on the factory wires leading up to the lights.
