Step 7
Your installation is now complete. Reattach the grille/
bumper assembly back to the vehicle in reverse order
of removal. Make sure you reconnect all disconnected
wiring harness and reattach all clips and screws. Wire
the LED Light Bar via our optional wiring harness kit
(part# 639HAR1) or custom wiring harness. Light bars
are installed ush with the grille from the factory. This
may or may not be ideal for each light depending on
the conguration of your vehicle and its options and
or modications. To adjust the angle of your Light Bar,
rotate the Light Bar to adjust the angle, then tighten
the hardware once the desired angle is achieved
(please be careful not to over tighten the mounting
hardware or scratch the nish of the grille). It is best to
adjust the angle with the vehicle on level ground with
lights facing a wall, garage door or other solid barrier.
We recommend checking from a distance of 25’. (Fig 7)
