This Bus Interface Module has inputs for up to three temperature sensors, Dakota Digital part number SEN-04-5.
Each input can be configured individually. There are two interface (I/O) ports on the module. Either one can be
connected to the gauge system or to another module, allowing several units to be daisy chained together. Do not
connect the I/O port to anything other than a Dakota Digital gauge or BIM. Do not mount the module in the engine
compartment; it should be mounted in interior of the vehicle.
Each sensor connected to the bus needs a unique ID number assigned to it. This module has three inputs so it can
use one, two, or three ID numbers. Each of the three inputs can be assigned an ID from 1 – 16, or turned off. The
factory default ID numbers are 1, 2, and OFF for the three inputs respectively. The factory default labels are TEMP for
all inputs.
Labels available for each input are:
TEMP -
generic temperature input. This will display TEMP x, Tx, or TEMPERATURE CHx where x is a
number from 1 – 8 corresponding to the module ID number. ID’s over 8 will start over at 1.
WATER -
dual water temperature input for right hand side water temp sensor. When this is active the gauge
system water display will show the higher of the left and right sensors. The message display will show
both temperature readings side by side. The gauge system water temp sensor should be installed in
the left hand side.
OIL -
oil temperature input. This will display OIL, OT, or OIL TEMP.
TRANS -
transmission temperature input. This will display TRANS, TT, or TRANS TEMP.
DIFF -
rear differential temperature input. This will display DIFF, DT, or DIFF TEMP.
Specs for each input are:

Temperature unit will follow the unit set for the main water temp gauge, Fahrenheit or Celsius.
The sensor has 1/8” NPT threads. Adapters are available to convert to other thread sizes.
