1. Install the Strobe Power Supply in a protected location using
the Power Supply itself as a template. THE POWER SUPPLY
MUST BE MOUNTED TO A METAL SURFACE. Make sure all of the
connectors are easily accessible. The unit is mounted using the
4 mounting holes on a 6” x 2.5” rectangle.

3. String the 3 conductor cables between the lights and Power
Supply. Make sure the cable is secure along the chosen routing
inside the vehicle to prevent it from damage by chafing or binding.
Be sure to keep the cable away from engine HOT spots.
When routing the cable, make sure the end with
the closed tip terminals (male pins) is toward
the Power Supply and the end with the open tip
terminals (female pins) is toward the light head.

4. Insert the pins on each end of the conductor cables into the
amp connectors. Each end of these cables has a factory crimped
pin on each of the three wires, see Figure B.
POWER WIRE HARNESS ASSEMBLY
The Power Wire Harness Assembly consists of an amp 3 pin
connector with red and black wires to supply power and ground,
and a violet wire to select different patterns, see Figure D.
NOTE
It is important to follow the correct color code
when inserting the pins into the amp
connectors.

see Figure A. Use 18 gauge wire to extend the proper Flash
Control Harness wires to a customer supplied switching system.
To extend the power (+) and ground (-) wires,
use the following as a guide:
1 to 10 ft. use 18 AWG Wire
10 to 20 ft. use 16 AWG Wire
20 to 30 ft. use 14 AWG Wire
30 to 50 ft. use 12 AWG Wire

The Power Wire Harness is connected to the Power Input Socket
located on the Strobe Power Supply, see Figure A. If necessary,
use 18 gauge wire to extend the violet wire to a customer supplied
switching system, see Figure G. Connect the red wire to the
positive (+) side of the battery making sure to place a customer
supplied 15 amp fuse at the battery. Connect the black wire to the
negative (-) side of the battery or to the vehicle chassis.
