HARNESS
INSTALLATION
When connecting the wires on the harness, follow the
wiring diagram and the sequence below.
Before connecting any wires the negative (-) battery terminal should
be disconnected.
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.
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.
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.
Splice the power wire for the marker lights to a source that will give them
the desired function. (i.e. parking lights, headlamp low beams or headlamp
high beams)
Plug harness into lamps.
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.
Aim lamps according to Light Aiming instructions on page 5.
Tighten all fasteners.
