              MAN 650314:D 

SPD – 
 

This terminal is used for speed sensor ground.  The wire color is BLACK on a 3-wire  

sensor.  This insures a proper ground as well as providing proper hook-up for a twisted pair of 
wires, or a solid state sensor.  Only ground the speed sensor here.  If you are using a single wire 
output from a computer for the VSS then this terminal should be left open.     
 
SPD OUT 
 

This terminal can be used to supply a speed signal to auxiliary devices such as a cruise 

control or radio volume adjustment.  The output is scaled to the input speed signal coming into 
the SPD SND terminal. It can be set to 2,000 PPM or 4,000 PPM. 

***If you are using the BIM-01-1 bus speed signal option this output will NOT work. 

 
SW2 (-) or Tach switch 

The SW2 terminal is used for selecting the various RPM, engine, and performance 

displays and also for entering the demonstration mode.  The SW2 input is activated by a ground 
connection.  The push button switch supplied (or any normally open, momentary switch) is wired 
by connecting one wire to SW2 and the other wire to a ground.  When the button is pressed and 
released, the tach/LCD2 message display will change.  When the button is pressed and held for a 
few seconds, any re-settable information displayed will be zeroed.   

To enter DEMO mode, press and hold SW2 while turning the key on.  The system will light 

up and say 

DAKOTA DIGITAL

 on the message readouts; release the switch and the system will 

stay in demo mode until the power is cycled off and back on without the switch held.  All back 
lights will be on in demo mode and the needles will sweep back and forth on the gauges.    
 
SW1 (-) or Speed switch 

The SW1 terminal is used for selecting the various speed, distance, and warning displays 

and also for entering the setup menu.  The SW1 input is activated by a ground connection.  The 
push button switch supplied (or any momentary normally open switch) is wired by connecting one 
wire to SW1 and the other wire to a ground.  When the button is pressed and released, the 
speed/LCD1 message display will change.  When the button is pressed and held for a few 
seconds, any re-settable information displayed will be zeroed.   

 

ADJ SND 

The ADJ SND terminal is an optionally used input that allows you to have control over the 

dimming brightness.  By default, the system will turn on the back lights when the DIM terminal 
has power, +12V, but this level is adjustable in the 

Lighting

 setup menu.  Using the ADJ SND 

terminal allows you to have a dash mounted control to vary the brightness while the headlights 
are on.  This requires Dakota Digital’s DIM-1 kit; a stock headlight rheostat will not work.   

The DIM-1 has a WHITE/BLUE wire and a BLACK wire.  Connect the WHITE/BLUE to the 

ADJ SND terminal and the BLACK to ADJ - ground.  The dash mounted dimmer will only vary the 
display brightness when the DIM terminal has power, +12V.  
 
ADJ –  
 

This terminal provides a ground reference for the optionally installed DIM-1 for dash 

mounted dimming control.  The BLACK wire will connect to the ADJ – terminal, the  
WHITE/BLUE connects to the ADJ SND. 
*This terminal should not be used for grounding any other sensors or devices as damage 
to the control box will occur.  If not using a Dakota Digital DIM-1, this terminal should be 
left open.
