Clock Instructions
For VFD systems with a clock built in
If you purchased your instrument system with an optional clock, it must be wired separately. The clock displays the current time in 12 hour format. The digital clock from Dakota Digital incorporates the reliability and quality of our standard gauges. These features include:
∙Quartz accuracy
∙Night dimming feature
∙Very low standby power to prevent battery drain
∙High visibility VFD display for sunlight readability
Wiring:
Clock
BLACK | Connect to a good ground point in the vehicle |
RED | Connect to switched 12 volt power point |
| (An accessory terminal will work for this) |
ORANGE | Connect to a constant 12 volt power point |
| (This will keep the correct time) |
BLUE | Connect to the taillight circuit |
| +12V when lights on for dim function |
Operation:
The gauge needs the red, orange, and black wires connected to operate. The red wire should have switched 12 volt power from an ACC. point on the fuse panel. The orange wire should have constant 12 volt power. The black wire should be connected to a good ground point. When the blue wire has 12 volts, it will dim the display for night viewing, this may be wired along with the wire to the DIM terminal on the control box.
