Mounting
Consult your local and state regulations regarding minimum and maximum mounting height above the
ground, or specific requirements. Mount both of the lamps at the same height. Nudge bars, light bars
and bull bars make excellent mounting platforms. Position the lamps at an equal distance from the
centre of the vehicle. Make sure the driving lights do not restrict airflow to the radiator or obstruct the
headlights, turn signals, or parker lights.
Installation
Using a test light, locate your vehicle’s high beam circuit. Most vehicles use a positive switching system
for high beam, but others such as some Toyotas use a negative switching system. This can be checked
at the back of the headlight or at the headlight switch loom.
To check for
positive switching
connect the test light to an earth and check for a positive wire that only
has power when high beam is switched on.
To check for
negative switching
connect the test light to a positive power supply and check for a wire
that only has an earth when high beam is switched on.
Once this has been established refer to the relevant wiring diagram.
Positive Switching
1.
Find a sheltered location in engine bay to mount relay away from extreme heat sources and
moving parts. Relay must always be mounted in an upright position.
2.
Connect a 4mm wire from terminal 86 on relay to a good earth.
3.
Connect a 5mm wire from terminal 87 to positive wires on driving lights.
4.
Connect 5mm wires from driving lights to a good earth (preferably to battery).
5.
Find a convenient position on dash board to mount driving light switch.
6.
Connect 3mm wire from ground terminal on switch to a good earth.
7.
Connect 3mm wire from power terminal on switch to high beam wire on vehicle.
8.
Run 3mm wire from load terminal on switch through the fire wall to the terminal 85 on relay.
9.
Connect a 5mm wire via a fuse from terminal 30 on relay to positive battery terminal.
