Safety First
This document provides all the necessary information to allow your Whelen product to be properly and safely installed. 
Before beginning the installation and/or operation of your new product, the installation technician and operator must 
read this manual completely. Important information is contained herein that could prevent serious injury or damage.
• Proper installation of this product requires the installer to have a good understanding of automotive electronics, 
systems and procedures.
• If mounting this product requires drilling holes, the installer MUST be sure that no vehicle components or other 
vital parts could be damaged by the drilling process. Check both sides of the mounting surface before drilling 
begins. Also de-burr the holes and remove any metal shards or remnants. Install grommets into all wire passage 
holes.
• If this manual states that this product may be mounted with suction cups, magnets, tape or Velcro®, clean the 
mounting surface with a 50/50 mix of isopropyl alcohol and water and dry thoroughly.
• Do not install this product or route any wires in the deployment area of your air bag. Equipment mounted or 
located in the air bag deployment area will damage or reduce the effectiveness of the air bag, or become a 
projectile that could cause serious personal injury or death. Refer to your vehicle owner’s manual for the air bag 
deployment area. The User/Installer assumes full responsibility to determine proper mounting location, based on 
providing ultimate safety to all passengers inside the vehicle. 
• For this product to operate at optimum efficiency, a good electrical connection to chassis ground must be made. 
The recommended procedure requires the product ground wire to be connected directly to the NEGATIVE (-) 
battery post.
• If this product uses a remote device to activate or control this product, make sure that this control is located in an 
area that allows both the vehicle and the control to be operated safely in any driving condition.
• Do not attempt to activate or control this device in a hazardous driving situation.
• If this product contains strobe light(s), halogen light(s) or high-intensity LEDs, do not stare directly into these 
lights at a close distance. Momentary blindness and/or eye damage could result. 
• If this product contains strobe light(s), halogen light(s) or high-intensity LEDs, use only soap and water to clean 
the lamp lens. Use of other chemicals could result in premature lens cracking (crazing) and discoloration. Lenses 
in this condition have significantly reduced effectiveness and should be replaced immediately. Inspect and 
operate this product regularly to confirm its proper operation and mounting condition. Do not use a pressure 
washer to clean this product.
• It is recommended that these instructions be stored in a safe place and referred to when performing maintenance 
and/or reinstallation of this product.
• FAILURE TO FOLLOW THESE SAFETY PRECAUTIONS AND INSTRUCTIONS COULD RESULT IN DAMAGE TO 
THE PRODUCT OR VEHICLE AND/OR SERIOUS INJURY TO YOU AND YOUR PASSENGERS!

Mounting:
This box requires a mounting plate secured to the motorcycle’s luggage rack. If the bike is not 
equipped with a mounting plate, one must be fabricated prior to installation of this box. Five 
mounting holes (.281” dia.) are required to mount this box.
If the motorcycle is already equipped with a mounting plate, it may be necessary to drill the 5 
mounting holes required for this installation.
Use the diagram shown to determine the precise location of these holes.
1. Position the box onto the mounting plate. Align the 5 vibration dampeners with the 5
5”5”
6.37”
mounting holes in the mounting plate.
2. Using the illustrations shown, secure the box to the mounting plate using the provided 
hardware.
NOTE: Your luggage rack may already have the correct mounting holes drilled. Check 
the measurements below and if these holes already exist at the proper distance, 
remove any existing mounting hardware from the holes and secure the box with the 
supplied mounting hardware.
3. Place the box into its mounting position on the deck and secure it with the 
supplied mounting hardware as shown in the diagram. 
Wiring:
Diagrams for optional equipment are shown below and on the following page. Refer to the 
diagram(s) on the following page for general motorcycle box wiring information.
WARNING: All customer supplied wires that connect to the positive terminal of the 
battery must be sized to supply at least 125% of the maximum operating current and be 
FUSED at the battery to carry the load. DO NOT USE CIRCUIT BREAKERS WITH THIS 
PRODUCT!
Operation:
Flash Pattern Selection: Lights must be switched on to use Scan-Lock™
TO CYCLE THROUGH ALL PATTERNS: Apply +12 volts to the WHT/VIO wire for less than 1 
second and release to cycle forward. Apply +12 volts to the WHT/VIO wire for over 1 second 
and release to cycle backward.
TO SET A PATTERN AS DEFAULT: When the desired pattern is displayed, allow it to run for 
more than 5 seconds. The lighthead will now display this pattern when active.

TO RESET TO THE FACTORY DEFAULT PATTERN: Turn off power, apply +12 volts to the 
WHT/VIO wire, then turn power on.
Note: If the installer wishes to connect the pattern selection wire (WHT/VIO) to a switch, 
a momentary switch (normally open) is recommended.
Outlet Activation:
Apply +12VDC to a control wire(s) to activate the outlet. The outlet(s) remain active until 
voltage is removed. Note: This flasher uses low current switching (100mA per control wire)
Low Power Operation:
Apply +12VDC to the VIO wire for Low Power Operation. Low Power Operation will remain in 
effect until voltage is removed from the VIO wire. An SP/ST switch is recommended.
Flash Pattern Phase Modes:
The flasher used in this application has 3 different phase modes. Each pattern is available in 
each mode. Each mode effects the relationship between each outlet: Phase 1 - 1, 3, 5 & 7 
alternate with 2, 4, 6 & 8  Phase 2 - 1, 2, 3 & 4 alternate with 5, 6, 7 & 8  Phase 3 - All flash 
simultaneously
