How to Install All Hardware on the Light Bar

How to install offroad led light bar with a wiring harness

Step1: Arrange LED light bar, mounting foot, and short Allen head bolt as show

Step 2: Slide Allen head bolt through leg mount and thread it into the side of the LED light bar, Position leg as desire and tighten by hand

Step 3: Using a 6mm Allen wrench, turn Allen head bolt clockwise until tight

Step4: Arrange longer Allen head bolt,leg mount, rubber foot mounting pad, and 10mm nut as shown

Step 5: Slide Allen bolt through led mount, rubber pad, and thread nut on to bolt by hand until snug

Step 6: This hardware is used when mounting your light bar, A 10mm wrench will be needed to hold the bottom bolt while tightening the Allen bolt

Step 7: Straight/Curved series light bar hardware shown correctly installed. Repeat the previous steps on the remaining mounting leg to complete the installation

WIRING INSTALLATION INSTRUCTION

Disconnect ground connection from the battery (-) to avoid accidental short circuits before attempting to connect electrical wires.
When running wires, avoid areas of excessive heat, vibration, pinch, or rotation when securing harness to vehicle.
Always use a fused (+) positive supply source.
This light becomes hot under continuous use. Do not remove or touch the casting for at least 30 minutes after the lamp has been turned off.

NEW VISION recommends using a professional for this installation. Refer to Wiring Harness Draw below

Locate the wiring harness and mount the switch in a convenient location where it is easily accessible from the driver’s seat. Note: The switch will need to be removed from the wiring harness so that the rest of the harness can be routed from the engine bay to the cabin.
Route the wiring harness wire, specifically the fuse and relay, from the positive battery terminal along the firewalls exist- ing wire routes. Note: Tape as necessary to correct slack.
Secure the relay by either drilling or using a pre-existing bolt along with the chassis that is not connected to any other wire.
Run the switch harness through the firewall preferably through the pre-existing rubber plug that is used to run the OEM wiring harness from the engine bay to the fuse box. Note: Reconnect the switch to the wiring harness.
Place the LED plug wire along with the fender chassis where it will not get pinched and away from any moving parts (fan, pulleys, etc.).
Run the attached wire from the LED Light Bar as previously mentioned away from any moving parts.
Connect both ends of wiring connectors from LED light bar and wiring harness.
Re-connect battery terminals, attach the red (+) wire to battery positive, and the black (-) wire to ground. Note: A dd dielec- tric grease (not supplied).
Turn on the switch to make sure if the light works. If not, please check carefully if the wiring installation is correct.

Troubleshooting

Light does not light

Make sure the switch is in the “On” position
Check in-line fuses
Make sure all connections are tight and not lose
Check wiring to make sure it is not damaged
Check voltage input on the red wire of pigtail across the black wire on pigtail
Check fuse box (If the switch is connected to it)

FAQ

Q1: When wiring the power for the switch, does the power need to run through the relay or can the power for the switch be directly from the battery?

A: The constant power to the switch can run directly through the battery

Q2: Can do a video to explain the wire thickness awg for each job

A: We usually use 16 to 14 gauge wires. And we have found that enough for LED light bar even 50 inch.

Q3: Where did you connect the positive and negative wire on the switch

A: Doesn’t matter, switches only serve as a way to break the circuit, positive and negative is irrelevant

WARNING

Failure to follow these instructions could lead to death, personal injury, and/or property damage.

Make sure all wiring is away from hot surfaces and moving parts.

After installing lights be sure to position lamps so they do not blind other drivers. Position your vehicle approximately 25 feet from a wall. The top of the beam projected on the wall should be 4 inches lower than the center of the light.

FASTENERS:

All New Vision supplied fasteners must be utilized and installed in accordance with the installation in- instructions and apply torque to the specifications as defined. DOUBLE CHECK ALL FASTENERS BEFORE INITIAL USE, AND PERIODICALLY IN THE FUTURE TO ENSURE PROPER FUNCTION AND SAFETY.

DRILLING:

Most NV products do not require drilling for installation. If drilling is defined as required, use caution when drilling a vehicle. FAILURE TO REVIEW AN AREA TO BE DRILLED MAY RESULT IN PERSONAL INJURY AND/OR INJURY TO OTHERS AS WELL AS VEHICLE DAMAGE.
