OPERATION.

SAFETY MESSAGE TO OPERATORS

Peoples’ lives depend on your safe use of our products. Listed

below are some important safety instructions and precautions you
should follow:

Although your warning system is operating properly,
it may not be completely effective. People may not
see or heed your warning signal. You must recognize
this fact and continue driving cautiously.

Also, situations may occur which obstruct your
warning signal when natural or man-made objects
are between your vehicle and others, such as: raising
your hood or trunk lid. If these situations occur, be
especially careful.

At the start of your shift, you should ensure that the
light is securely attached and all lamps are operat-
ing properly.

If a selected function does not perform properly or if
any of the lamps remain illuminated when the
control is off, disconnect the power connector from
the control unit and contact the nearest service
center.

Failure to follow these safety precautions may result in

property damage, serious injury, or death to you, to passengers, or
to others.

CAUTION

When connecting the right angle terminals to connectors
H1 and H2, support the circuit board to avoid breaking
the terminals or cracking the printed circuit board.

See figure 3. Connect the two right angle

terminals to connectors H1 and H2. Note which wire is attached to
H1 and to H2.

e.

Slide the lens mounting plate into the extru-

sion. Route the 22-gauge wires through the grommet. Secure the
end plate on the light assembly using the previously removed
screws.

Route each 22-gauge wire to the appropriate

turn signal lamp socket. Connect the wire from H2 to the right
turn signal lamp power wire. Connect the wire from H1 to the left
turn signal lamp power wire.

D.

Inspection and Final Installation.

1.

Ensure that there are no loose wire strands or other

bare wires which may cause a short circuit. Also, all wires must be
protected from any sharp edges which could eventually cut
through the insulation.

2.

Connect the 14-gauge red wire to the (+) positive

terminal of the battery using an in-line, user-supplied fuseholder
and 15A fuse. Locate the fuse as near the battery as possible to
protect the entire length of wire.

NOTE

All directional lamps will illuminate simultaneously if
the power supply leads are reversed. Correct the wiring
before proceeding.
