INDICATORS
The right turn, left turn, and high beam indicators are activated by 12 volts at their respective hook-up wires. The right turn
signal wire is GREEN, the left turn signal wire is ORANGE, and the high beam wire is PURPLE.
The neutral, low oil, and check engine indicators are activated by ground at their respective hook-up wires.
The check engine wire is PINK, the low oil wire is BROWN, and the neutral wire is WHITE/GREEN.
These can be connected to the signal wires for the original indicator lights.
The display system wire colors may not match the wire colors in your electrical wire harness; consult a service manual to
determine the color code and location of any wires you cannot locate.
The WHITE output speed signal normally attaches to the GREEN/WHITE wire of a stock Harley turn cancelation module.
Aftermarket TCM modules, that do not use speed to self-cancel turn signals, will not need this wire.
OPTIONAL OIL TEMPERATURE
Dakota Digital part number SEN-1043 or SEN-1044 must be used. The SEN-1043 is a one-wire sender with 1/8” NPT
threads. Connect the terminal on the end of the sender to the indicator harness BLUE wire. Because this sensor grounds
through its body, ensure sure the sender threads are able to make a metal-to-metal connection to complete the ground.
The SEN-1044 is a two-wire sender with 3/8” NPT threads. Connect the sender red wire to the indicator harness BLUE
wire and connect the sender BLACK wire to the indicator harness BLACK wire.

OPTIONAL OIL PRESSURE
Dakota Digital part number SEN-1039 must be used. The sensor red wire connects to the indicator harness WHITE/RED
wire, the sensor WHITE wire connects to the gauge GRAY wire, and the sensor BLACK and BARE shield wires connect
to the indicator harness BLACK wire.
The BROWN “Low Oil Warning” wire will not be used with the SEN-1039, only with a stock low-pressure switch.
