POWER HARNESS:
• Connect the RED wire to battery positive (+) or a fuse panel circuit
rated for at least 15 AMPS.
• Connect the BLACK wire to battery negative (-) or directly to vehicle
chassis.
Note: Use the correct size wire for power connections.
The length of the wires determines the size needed.
1 to 10 ft. use 18AWG wire.
10 to 20 ft. use 16AWG wire.
20 to 55 ft. use 14AWG wire.
35 to 50 ft. use 12AWG wire.
• The VIOLET wire controls HIGH / LOW power. Low power limits the
flash intensity for nighttime use. Connect VIOLET to +12/24V for LOW,
leave VIOLET disconnected for HIGH.

Strobe Head Outlets
2.Strobe Head installation
Plug the strobe light heads into the outlets. Keep the following in
mind:
• Heads connected to outlets 1 and 3 flash at the same time.
• Heads connected to outlets 2 and 4 flash at the same time.
• Heads connected to 1 and 3 alternate with heads 2 and 4.
The output power divides equally between all strobe heads
installed. Example: 90 Watts into 2 heads = 45 Watts per head.
Consider this before selecting the number and type of strobe
heads to install. Do not exceed the wattage rating of the head.
Note: This supply reduces output power when 2 outlets are
activated.

1.Physical Mounting
Mount the power supply in a clean, dry location. Mounting the unit
to a flat metal surface will aid in heat dissipation. Use the power
supply as a template to mark the hole locations. The mounting
holes will accept up to a 1/4” bolt. Note: The power supply baseplate must be connected to chassis ground (GND) to reduce radio
interference.

CONTROL HARNESS:
• YELLOW, GREEN, BLUE wires select the flash pattern and also
control which strobe head outlets are activated. A wire is ‘selected’
when connected to +12/24V. When all control wires are unconnected
the power supply is in a low current SHUTDOWN MODE (Current
is typically 25ma). See the PATTERN TABLE on the next page for a
complete list of functions.
Note: VIOLET, YELLOW, GREEN, BLUE, WHITE, and ORANGE
are all Low Current circuits and can be wired with a minimum of
22AWG wire.
Heavy duty extension cables have a GREEN wire,
Light duty extension cables have a RED wire.

NORMAL: The OUTPUT INDICATOR will light when ANY strobe head fires. It
will blink in exact time with the flash pattern. When the X-PAK 754 is turned off
the indicator may dimly blink for a few seconds. This indicates that the power
supply is discharging itself.
PROBLEM: If the X-PAK 754 is activated but none of the strobe heads are firing, check the OUTPUT INDICATOR. If the light is blinking or on steady then it
indicates that there is a short circuit on one or more of the strobe head outputs.
To find the short circuit, unplug all strobe head cables from the X-PAK 754. Test
one cable/head at a time until the problem is found. Do not test with more
than one cable/head installed.
The problem is typically at the strobe head end of the cable. If there is a blue/
green or black colored corrosion on the connector it is shorted.
Also check for a head or cable with a reverse wired connector.

firing, check the INPUT INDICATOR. If it is ON then it indicates that the input
voltage is too low (below 10V). There may be a bad connection to the battery
or ground. If the X-PAK 754 is functioning but the INPUT INDICATOR is blinking or lit, it indicates that the voltage is too low and the power supply is not
operating at full power. Check for bad connections and be sure the proper size
wire was used for the + and - connections.
