Option 3) Voltage input harness - The module can be ordered with a voltage input harness. This
harness provides two ‘flying lead’ input wires. Both wires are inputs and can accept
a 5 – 17 volt input signal from a switch or light controller of your choice. The white
wire corresponds to switch input 1 and the green wire corresponds to switch input
2. Each input can be configured for specific lights or patterns using the STE
Configuration Utility. This option is designed for users who want to use their own
switch or controller to activate the device.
Active Modes
EFM 3.0 has five active modes that can individually be configured for both flash pattern and active
lights. Configurations can be modified using the STE Configuration Utility available for free download
on the support page of our website. Active modes are shown below in order of priority:
• Park Mode – Park mode is active when switch input 1, switch input 2, or the integrated
vehicle switch is active and the vehicle transmission is in park. Park mode pattern and active
light configurations take precedence over any switch configurations. Park mode is disabled
by default. This mode is useful for users who want to disable certain lights in park or change
the pattern.
• Switch Input 3 Mode (virtual) – Switch input 3 mode is active when the input to switch input
1 and switch input 2 is between 5 – 17 volts. This mode is only available for use with the
voltage input harness. Switch input 3 mode pattern and active light configurations take
precedence over switch input 1, switch input 2 and integrated vehicle switch configurations.
Switch input 3 mode is disabled by default. This mode is useful for users who want a front
rear split. Configure switch input 1 for your front lights, switch input 2 for your rear lights
and switch input 3 for all lights.
• Switch Input 1 Mode – Switch input 1 mode is active when the toggle switch harness is in
the ON position or when the input to the white wire of the voltage input harness is between
5 – 17 volts. Switch input 1 mode pattern and active light configurations take precedence
over switch input 2 and integrated vehicle switch configurations.
• Switch Input 2 Mode – Switch input 2 mode is active when the input to switch input 2 is
between 5 – 17 volts. This mode is only available for use with the voltage input harness.
