First locate your speedometer and tachometer connectors in the factory wiring harness that where unplugged from the
original speed and tach gauges. Plug these connectors into their correct locations on the adaptor box. The adapter box
has one set of connectors for 1996-1999 applications and another set for 2000-2003.
For cable driven speedometers you will also need to wire in a speed sensor. If you have provisions for a transmission
mounted sender use Dakota Digital SEN-1017, if not use Dakota Digital SEN-1011 a cable driven speed sensor. Wiring of
the speed sensor will be done using the supplied 3 wire pigtail that connects to the adaptor box. The speed sensor pigtail
should have a Red, Black, and White wires with a 3 pin connector. The speed sensor will need to be connected to the
pigtail following the table below. Cut the red wire back if using the cable drive adaptor SEN-1011 since it is not used.

If you are using the cable driven adaptor you will also need to pull the speedometer cable from the front wheel and
replace the cable nut with the supplied cable nut so your speedometer cable will thread onto the new sender. You have to
take the cable off at the wheel so the nut can slide down and off the end of the cable and allow the new nut to slide on.
After the nut has been replaced the speedometer cable can be connected back to the wheel and also to the sender.
Secure the sender with a zip tie and make sure there is no binding in the cable and that the cable has engaged fully into
the sender.
Speedometer connector
To connect the adapter box to the speedometer you will need the supplied harness (this may already be connected to the
adapter box). This harness has one 16 pin connector and one 12 pin connector. The adapter box will attach to the 16 pin
connector. The speedometer will attach to the 12 pin connector.
Clock Memory connection
You will need to locate a fused, co12V battery power wire for the orange, clock memory wire. The long, orange,
clock memory wire is located on the speedometer gauge plug. Check your service manual or use a voltmeter or test light
to find and verify a constant power location. One common location to pick up the constant power is pin #10 on the radio.
This should be a Red w/Orange wire that is fused to the battery.
The 3-pin connectors on the back of the speed and tach provide the sender
connections. The speed 3-pin connector provides ground, fuel level, and air
temperature with spade connectors for easy connection to the factory plugs. The
tach 3-pin connector provides oil temperature and oil pressure. Connect the speed
3-pin yellow wire to the factory fuel gauge connector yellow wire. The speed 3-pin
black wire is the main system ground; connect it to the fuel gauge connector black
wire. Connect the speed 3-pin blue wire to the air temperature gauge connector
blue wire. Connect the tach, 3-pin, brown wire to the oil pressure gauge connector
brown wire.
A 4-pin, three wire harness with six connectors is included. This will plug into the
back of each gauge, these wires provide power, ground, and data. Route one of
these harnesses to the back of each gauge and plug it in. It does not matter which
connector goes to each gauge.
Use provided zip ties to secure
connections and loose harnesses.
