Dakota Digital Gauge Installation

This sheet covers the installation of the Dakota Digital gauge kit into the original clusters.

1. Remove the clusters from the vehic le. The procedure for the speedometer
and tachometer clusters are the same, but only one side is shown in the
photos.

2. Remove the three screws holding the bezel on to the gauge can. Two are
indicated by the upper arrows in the photo at right; one is on the bottom side
of the can and cannot be seen here. After the bezel is set aside, remove the
two screws near the center of the can to remove the original gauge. On the
speedometer can (shown) you will also need to remove the trip meter reset
cable.

3. Use the provided flexible grommet mater ia l on the edge of the
mechanical cable openings on the original gau ge cans to protect the
ribbon cables. A few dabs of silicone will help hold it in place. Pass the
ribbon cables through the lined cable openi ngs until the gauge
assemblies sit into the cans and the cables are not being pinched.

4. Use four of the supplied #10-32 x .500” screws and lock washers
to secure the gauge assembly into the can. It is recommende d to start
all the screws before tightening completely. If the screw holes do not
line up properly, the gauge a s sembly is in the wrong can.

5. Re-install the bezels to the gauge cans using the screws removed in
step 2.

6. Remove the center gauge cluster from the vehicle. From the back
side, remove the four screws as indicated by the arrows in the photo at
left which hold the stock gauges to the bezel. The stock gauge
assembly can be set aside.

7. Leave the clear lens and gauge separator plate in the bezel and
install the four provided #6-32 x .625” standoffs in the holes that
you removed the screws from in the pr evious step. Take care not to
over tighten as the threaded portion standoffs can break.

8. Included are some lenses that can be used as block offs for the
openings at the sides of the top two gauges as indicated by the arrows
in the photo at left. Due to factory changes over the years, three
different sizes are provided. The small one is not square and will only
fit in one direction. Set these in place and secure with silicone.

9. Set the Dakota Digital gauge cluster onto the standoffs and use
the four #6-32 x .250” screws and lock washers to secure it to the
bezel. It is recommended to start all four screws before tightening
any completely.

When installing the cluster back into the vehicle connect the two
gray ribbon cables to those coming off the main cluster. The clock
will need to be wired separately. Two remote mount time set
switches are wired to the clock and will require 1/4” holes to be
drilled to mount them.

See the main instruction manua l for the remainder of the installation.

The Odyssey clock from Dakota Digital, Inc. incorporates the reliability and quality
of our standard gauges, along with several unique features and easy mounting. These
features include:

• Quartz accuracy.

• Night dimming feature.

• Very low standby power to prevent battery drain.

• High Visibility VFD display for sunlight readability.

MAN#650277

The Odyssey series clock displays the current time in 12 hour format. The high
brightness display matches our other Odyssey, STR, and VFD3 series gauges and has
the same night brightness dimming capability.

Operation:

The gauge needs the red, orange, and black wires connected to operate. The red
wire should have switched 12 volt power from an ACC. point on the fuse panel. The
orange wire should have constant 12 volt power. The black wire should be connected to
a good ground point. When the blue wire has 12 volts, it will dim the display for night
viewing.

Setting the time:

The remote mounted red and black push buttons will be used to set the clock. The
BLACK “set” button advances hours, the RED “set” button advances minutes. Each time
that you make a change to either the hours or minutes, the seconds are reset to zero.

Adjusting the accuracy:

The clock is accurate to +/-2 minutes a month as it is sent. It can be tuned for
better accuracy if desired. Press and hold both of the set buttons for several seconds.
The clock will display “C 0”. The “C” indicates that it is in the calibration mode and the
second number is the current calibration value. The calibration value indicates the
number of seconds to add or subtract each d ay. The clock can be adjusted from +7
sec/day to -7 sec/day.

Press the minute set button to change the cal value. Press the hour set button to
return to normal clock operation.

Wiring:

BLACK - connect to a good ground point in the vehicle.
RED - connect to switched 12 volt power point.
(An accessory terminal will work for this.)
ORANGE - connect to a constant 12 volt power point.
(This will keep the correct time.)
BLUE - connect to the tail light circuit.
