WTR SND
The water temperature sender included with this system must be used. Other
senders will cause incorrect readings or damage to the control box.
The supplied sensor, Dakota Digital
SEN-04-5
, is a 100-300ºF(40-150ºC) temp sensor.
The sender mounts on the engine block or into the intake manifold so that the end of the sensor
is in the engine coolant flow. It has 1/8” NPT threads and the included adaptor bushings may be
used to adapt it for various applications.
To avoid mounting an additional temperature sender on the engine, a Dakota Digital
BIM-
01-1
may also be used with most 1996 or newer OBDII compliant computer systems to provide
an engine temperature reading. When using the
BIM-01-1
, select “
BUS F
” or “
BUS C
” for the
sender type.
The water temp sensor has two wires coming from the harness. The BLUE or RED wire
will connect to the WTR SND terminal, the BROWN or BLACK wire will connect to the WTR –.
Due to the construction of the sensor, readings at temperatures below 100 ºF may be
inaccurate. The sensor is designed to be accurate from approximately 100 ºF - 300 ºF.
WTR –
This is the ground reference used for 2-wire water temp sensors. This will connect to one
of the BROWN or BLACK wire from the Dakota Digital
SEN-04-5
. The BLUE or RED wire will
connect to the WTR SND terminal.
***DO NOT connect this terminal to any other devices
OIL +
This terminal is used to supply power to Dakota Digital pressure sensor
SEN-03-8
. This
supplies 5V DC to the sensor and should not be connected to anything else. Connect the RED
wire from the SEN-03-8 to this terminal.
***DO NOT use this terminal to power any other devices; it is a low c5V output.
OIL SND
The oil pressure sender included with this system must be used. Other senders
will cause incorrect readings or damage to the control box.
The supplied sensor, Dakota Digital
SEN-03-8
, is a 0-100 psi solid state pressure
sensor. The sender can mount on the engine block or in an oil pressure line off of the block.
The sender has 1/8” NPT threads. The included adaptor bushings may be used to adapt it for
various applications.
The oil pressure sensor has three wires coming from the harness, plus one bare shield
wire. The WHITE wire will connect to the OIL SND terminal, the RED to OIL + (5V DC), and the
BLACK and bare shield wire to OIL –. Do not route the oil sender wire alongside a spark plug
wire or other high current or high voltage wires. Doing so can cause incorrect or erratic gauge
readings.
If the oil pressure drops below an adjustable warning point, the reading will flash as a low
oil pressure warning. The default warning point is 10 psi. If the oil display shows “---” this
indicates that the control box is sensing an open circuit, a short to ground, or out-of-range error
from the sender or sender wire. If the oil display shows “
EEE
” this indicates that the control box
is sensing a short to power or an out-of-range error from the sender. If either indication remains
on the display, inspect the sender wire for damage, check the routing of the sender wire, check
the sending unit grounding, and check that the correct sending unit is connected.
