HARNESS
INSTALLATION
1. Before connecting any wires, the negative (-) battery terminal should be disconnected.
When connecting the wires on the harness, follow the wiring diagram and connect
them as in the diagram.
2. For proper lamp operation it is recommended that you connect the positive (+)
and negative (-) power supply wires directly to the corresponding battery terminals.
Do not take power directly from the alternator.
3. Find a power source to connect the switch power wire to. For legal operation of
driving lights, the power source must be one that is only powered when the high
beam of the headlamps is on. To make this connection use the supplied connector
or any connector that is suitable for this application.
Do not connect lights to turn signals or to lights that flash with
an automotive alarm.
4. When running the wires through the engine compartment be sure to keep them
securely away from moving parts such as the fan and the throttle cable and away
from hot parts such as the exhaust manifold.
5. When the wiring is complete, test the system for operation. Do this by turning on
the system. If the system works, securely fasten the relay boxes and fuse holders
or tie them out of the way with wire ties. If the system does not come on, please
contact your PIAA dealer for assistance.
