DIRECT NOSEBOX INSTALLATION GUIDE
Interior Light Control Timer
When there are 3 minutes remaining on the timer, the interior lights (inside
the trailer, as well as the LED indicator on the front of the nosebox) will blink
3 times. At 2 minutes, the lights will blink 2 times; at 1 minute, they will blink
once.
If the interior trailer lights are on, and the system detects power on the 7-way
aux pin, the timer will automatically set to 3 minutes to ensure the interior
trailer lights are turned o while the vehicle is in motion.
If the battery voltage is below 12.2 volts, the timer will automatically set to 3
minutes to preserve the battery.
