TACH OUT
• This terminal can be used to supply a buffered tach signal to auxiliary devices such as a cruise
control.
***If you are using the "bus" tach signal option, with the output from a BIM-01-X module,
this output will NOT work.
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 SIG terminal. It can be set to 2,000 PPM or 4,000 PPM.
***If you are using the GPS speed signal option or the bus speed signal option, with the
output from a BIM-01-X module, this output will NOT work.
CRUISE (-)
• The CRUISE terminal can be used as a "cruise engaged" indicator. The CRUISE input is
activated by a ground signal from a compatible cruise control harness. Whenever the CRUISE
input is grounded, the system will display a small green "cruise engaged" indicator.
SPEED INPUT - PWR
• This terminal is used to supply power to Dakota Digital speed sensor SEN-01-5. This supplies
5V DC to the sensor and should not be hooked up to anything else. Connect the red wire from
the SEN-01-5 to this terminal.
• If you are using a 1-wire VSS output from a computer or a two-wire pulse generator this
terminal should be left open.
***DO NOT use this terminal to power any other devices; it is a low current +5V output.
SPEED INPUT - SIG
• This is where the vehicle speed sensor (VSS) connects. The signal supplied to this terminal
will be used by the Control Box to calculate the speed reading on the display and also for
calculating and saving odometer mileage. If a BIM-01-x module is used to obtain the
speedometer reading then this terminal will not be connected.
• Dakota Digital supplies a 3-wire sensor for most of its kits, SEN-01-5. If you are using this
sensor, the white wire is the speed signal; connect to SPD SIG. The red and black wires in the
cable are power and ground (5V DC) and their connection is discussed in the SPEED INPUT –
PWR and –GND sections.
• For two wire speed sensors such as a cable driven pulse generator, the polarity of the wires
does not matter. Connect one wire to the SPEED INPUT - GND and the other to the SPEED
INPUT - SIG terminal. The speed sensor ground wire should be brought back to the Control
Box to ensure a proper signal is received. Twisting the ground and signal wires around each
other provides an additional level of interference protection. The speed signal wire should not
be routed alongside tach, ignition, or other high current or high voltage wires.
• For vehicles which have a vehicle speed signal from a transmission sensor or ECM, tap into
the VSS wire and connect it to the SIG terminal. Consult a vehicle service manual or wiring
diagram to determine wire color and location.
• This system can accept 2,000 ppm – 250,000 ppm speed signals. The speedometer is fully
adjustable and calibration is discussed in a later section. The TFT will display "PLEASE
CALIBRATE SPEED" in the Message Area until the speedometer has been calibrated.
***Failure to calibrate the speedometer may cause your odometer mileage to increase
very rapidly if the speedometer is reading too fast.
*** The speed signal wire should NOT be routed alongside ignition or other high
current/voltage wires.
SPEED INPUT - GND
• This terminal is used for speed sensor ground. Connect the black wire from the SEN-01-5
here. This insures a proper ground as well as providing proper hook-up for a twisted pair of
