PRIOR TO INSTALLING THE LIGHT BAR ON YOUR VEHICLE, HARDKORR RECOMMENDS
TESTING THE LIGHT BAR AND WIRING HARNESS OUTSIDE OF THE VEHICLE.
1. Disconnect the negative cable of the battery.
2. Choose whether to use the end-mount legs or under-mount legs. Attach whichever legs you are
using to the bar - see page 5 for further instructions.
3. If you do not have pre-drilled holes, sit the light bar on the mounting surface, mark where the holes
will need to be placed, and then remove the light and drill the holes.
4. Mount the light bar, ensuring that the rubber pads are in place where the legs contacts with the
mounting surface. Roughly align the bar to your desired angle, then tighten the bolts connecting the
bar and legs so that the bar does not move out of position.
5. Connect the 4-pin Deutsch plug cable from the light bar to the matching plug on the wiring harness.
6. The light bar incorporates a Daytime Running Light (DRL) that is capable of producing either
orange or white light. To connect the white DRL, you will use the white wire in the next step. To
connect the orange DRL, you will use the yellow wire.
7. Connect the DRL wire to the twin fuse adaptor (both blade and mini blade fuse adaptors are
included) then open your main fuse box and remove the accessories fuse. Plug the accessories
fuse as well as the supplied fuse into the adaptor, then insert the adaptor into the fuse box slot from
which you removed the accessories fuse. Cover the end of the other wire with electrical tape.
8. Remove the high beam plug from the back of your headlight and connect it to the piggyback
adaptor - the kit has a HB3 and H4 adaptor supplied, however other adaptors are available for
purchase separately if your vehicle has a different plug (see page 10) - note some modern vehicles
require an adaptor specific to that model. Connect the piggyback adaptor to the white plug on the
harness, and then reconnect the piggyback adaptor to the back of your headlight.
9. Next, feed the switch to the inside of the cabin. This should be through a rubber grommet that runs
through the firewall. To do this, you’ll need to note the order of the wires on the back of the switch,
then remove, reconnecting once in the cabin of your vehicle.
10. Secure the relay to the body of the vehicle then connect the positive and negative terminals from
the harness to your battery.
11 . After installation, we recommend you drive to a nearby location at night to properly set up the light
bar beam. Park the vehicle on a flat area from where you will be able to clearly see the light beam,
then switch on the light bar and loosen the bolts connecting the bar and legs. Adjust the angle of
the bar so that the ground in front of the car is well-lit but there are no ‘hot spots’ (areas where the
light is too concentrated). Once satisfied, re-tighten the bolts to ensure the bar stays in place.
