Wire Functions
Ground - Connect to the negative side of the battery.
Bare/Shield - Connect to the negative side of the battery.
Power (Red) - The Red wire MUST be connected to +12 VDC through your switch. Be sure to
use a 10 amp fuse when connecting the switch to the positive side of the power
supply.
Please note: When the red POWER wire is connected to constant power the
light will draw a small current (25 mA). If your vehicle will be sitting
for extended periods of time (i.e. more than a few days), it is
recommended all power wires be routed through an ignition
switched power source.
Front Enable - When the red POWER wire has power to it, applying +12VDC to the Front
Enable wire will switch only the front M-Tech Plus™ lights on.
Rear Enable - When the red POWER wire has power to it, applying +12VDC to the Rear
Enable wire will switch only the rear M-Tech Plus™ lights on.
M-Tech Plus™Pattern Select - • Activate only the M-Tech Plus™ primary warning lights.
• Connect the Red w/Green and Green wires together.
• Touch and release the Red w/Green and Green wires to
+12 VDC to scroll through the flash patterns.
• Pattern List on page 6.
Pursuit Light Pattern Select - Activate the Pursuit lights only, then touch and release to the
Red w/Green wire only to +12VDC to scroll through the flash
patterns for the Pursuit Lights (see page 7).
Sync - Connect to white wire from any other . compatible light and set the M-Tech
Plus lights for the same pattern type. See the instruction manual included with the
light you are synching for detailed programming instructions.
High/Low - Connect to the negative side of the battery (ground) for low power. Leave open (or
disconnected) for high power.
Additional components - If your bar contains any additional components including, but not
limited to, those listed below, applying +12VDC to the appropriate
If you do not need independent control of the front and rear M-Tech Plus™ lights, it is recommended that
you connect all THREE wires (Power, Front Enable, and Rear Enable) together through your switch.

!
The S8070-346-2**circuit, used in these lightbars (excluding the Amber Value versions), has Low Voltage
Detection. With this feature the circuit senses the input voltage and flashes a fast pattern (approximately
16 cycles per second) to indicate to the user that the battery voltage has dropped below 10V). Once the
input voltage returns to normal (greater than 12V) the unit will return to the normal flashing.
