BEFORE YOU BEGIN:
Read these instructions completely.
Plan out your wiring scheme ahead of
time. Use the included wiring diagrams to
help guide your wire routing
Use 14 ga. wire on all connections to
sending units.
Use electrical solder and heat shrink
tubing or appropriate solder less
connectors to make all wiring connections
Disconnect the vehicle's battery
Do not use thread sealer on the sending
units, they have a tapered thread
Have a plan. Mock up parts or layout as
needed. It takes a little more time, but will
save time and money in the end.
Recommended Tools and Materials
Needed for Installation
14 and 16 ga. stranded wire
Spade or Bullet connectors
Momentary push-button
Pressure sender for hour meter
Electrical solder (optional)
Heat shrink tubing (optional)
Soldering iron (optional)

Installation of gauges:
2. Slide gauge through hole and add
backing clamp over the retaining studs.
Using the included washers and nuts,
tighten to a snug fit
Wiring the gauges:
Run the power wiring from the gauges to an
appropriate positive (+) on the fuse block
after the battery. This applies to the
switched 12V+ and gauge lighting
Connect the ground to a good dedicated
ground on the chassis
Run each wire to the appropriate sender
and use the proper connector for each item
(eyelet, spade, etc.) from the sender to the
dash. Leave some extra slack in the wire
and label it.
Ensure that wires will not chafe on holes by
using grommets and that they will clear any
moving objects.
Once wires are run from the appropriate
sender location to the gauges location,
connect to the corresponding wire on the
Packard connector with solder and heat
shrink tubing or a solder less connector.
NOTE: The 4-3/8" speedometer lighting is
wired via tabs on the back. The bulb is a GE
194 The 3-3/8" speedometer lighting is LED
lighting which is internal, no replacement is
required.
Sender installation
You must use senders with the proper ohm
match for your gauge, using mis-matched
senders will result in improper readings on your
gauge.
Water temperature 450-29.5 ohm
The water temperature sender has a 1/8 NPT
end. It should be installed close to the
thermostat on the intake manifold. There are
usually ports for temperature on the block in the
water jackets, which can be used as well.
Oil pressure. 240-33ohm
The sender has a 1/8 NPT end on it. Check for
your factory location for a pressure port and
install.
Fuel level: 240-33 w/ sender, 0-90, 73-10, 0-30
The fuel gauge range (ohms) must match sender
1. Locate suitable positions foryour gauges.
The gauges fit in a 4-3/8" and/or 3-3/8"
holes. Take note of the anti-rotation
notches and add this feature where
required.

CALIBRATING THE ELECTRONIC SPEEDOMETER
With the key on, in normal operating position, press the remote pushbutton for
approximately 2 seconds. The word HELLO will appear in the odometer window
PUSH 2 SEC.
When the button is released, it will read "CLR ODO" scroll through the menu by
briefly pressing the button and the 3rd item will be "self HI"
PUSH BRIEFLY
2 TIMES
Wait 4 seconds and "PENDING will appear. The speedometer is now waiting for input
to start counting pulses per mile. Push the button, drive a measured mile, do not turn
off ignition, stopping and starting movement is OK. "SELF HI" will appear while driving.
wait 4 sec
At the end of the mile, push the button again, "CALCING" will appear briefly. Push the
button 2 more times to "DONE" your speedometer is now calibrated, enjoy. You may
repeat the process as many times as needed. The setting will be stored in the
CALIBRATING THE MECHANICAL SPEEDOMETER
Your mechanical speedometer has a universal 1:1 drive ratio. If your stock speedometer was accurate
before, this one has tyhe sdame drive ratio.
Calibration is achieved by changing the vqaroius drive grars in your transmission. Pleasce consult your
transmission shop for a selection of varoius gears.

NOTES:
The pointer may or may not move during calibration depending on the pulse count per mile
If the speedometer hangs at calculating, this indicates one of 2 things:
1. The speedometer did not recieve any pulses from the sender-check sender signal
2. The 2nd SELF Hi step was missed
SPEED SENDER TROUBLESHOOTING:
Check for power and ground if applicable
With a drill motor spin the sender with the key on and the sender removed from the transmission
Integrated speed senders /2 wire senders: should emit 8-18V AC sine wave with wheels spinning
ECU putputs: should emit 5 or 12V square wave signal, you will see 2.5 or 6v with wheels spinning

THE BASICS
This supplemental section will provide
information on the many functions
available in the programmable
speedometer. While some of the
functions may not be required for
each application, those functions are
available if needed in the future.
Odometer
The commercial speedometer
contains an odometer to maintain a
record of the total mileage and trip
mileage. During normal operations
and after a power on the odometer
display shows;
This display cannot be reset. A quick
press of the push-button changes the
display to the Trip odometer.
PROGRAMMABLE SPEEDOMETER SUPPLEMENTAL
Trip Odometer
The Trip odometer allows you to keep
a record of the trip miles or kilometers
independent of the Odometer
The Trip Odometer is fully user
resetable. While in the Trip Odometer
display press the push-button for 4
seconds and the Trip odometer is reset
to zero.
Hour-meter
The speedometer also contains an
hourmeter that can run continuously
when the ignition is on, or for a more
accurate engine hour operation, can
be turned off by using a low oil
pressure switch to deactivate it. This
will ground the Yellow wire on the 6-pin
harness disabling the hour meter when
the engine is running. The Quick
press the push-button while in the Trip
Odometer function displays the Hour-
meter.
USING THE MENUS
There ate two main menus and
several sub-menus in the
speedometer interface. Each area is
accessed with the provided remote
pushbutton.
-8-

RUN MENU
Pressing and holding the push-button
for two seconds during normal
operation will activate the "run menu"
The display will show "HELLO" and
wait for you to release the push-
button.
When the push-button is released the
first item on the menu will be shown.
In four seconds the microprocessor
will go to the first menu feature.
If you want a different item from the
menu, you must press and release the
push-button before four seconds have
passed. The menu items will loop
continuously. If you want to get out at
this point with no changes, stop at the
last menu item "donE", and in four
seconds the microprocessor will
return to normal with nothing being
changed or if you are in a menu, just
do nothing for 32 seconds and the
microprocessor will restart and
change nothing.
The first item in the run menu is
"ClrOdO" (Clear trip odometer).
If the operator stops at this display,
the microprocessor will reset the trip
odometer to zero and will return the
microprocessor to its normal
operation.
The second menu item "SET SPd"
(Set Speed) is used to set the speed
at which the over-speed indicator will
activate.
Stopping at this display and waiting
four seconds will set the display to
three digits corresponding to the last
speed that the over-speed was set to.
The leftmost digit will be flashing and
the change and implementation of the
input numbers are the same as
above. When the push-button is held
for four seconds the microprocessor
will set the number in the display to
be the new over-speed trip point.
The option to get out with no changes
is available by not making any
changes for 32 seconds.
Over Speed condition
An over-speed condition will ground
the orange wire on the 6-pin
speedometer connector. (maximum
40 milliamp load) on the speedometer
when a pre set speed has been
passed. This output can be utilized by
the customer to activate a warning
device such as a lamp or a buzzer.
The third menu feature "SELF HI"
(Self calibrate high axle) can be
activated by waiting at this display for
four seconds.
-9-

This is a feature to allow automatic
setting of the high axle pulses per mile
or kilometer that the speedometer will
use to position the pointer and record
the correct mileage. This is
accomplished by indicating to the
speedometer microprocessor, the
beginning and end of a measured mile
or kilometer. The microprocessor will
actually count the pulses that
occurred during that mile or kilometer
and compute the required parameters.
When this mode is activated the
speedometer will display "PEndInG ".
This means that the microprocessor is
waiting for the push-button to be
pressed indicating the beginning of
the measured mile or kilometer.
When the push-button is pressed and
released the display will change to
"SELF HI" indicating that the
microprocessor is now counting
pulses.
The speed at this point is not
important. The operator may even
stop and wait, as long as power is not
turned off and the measured mile or
kilometer is followed as straight as
possible, the operator may not
turn around and go in the opposite
direction. Also for the maximum
accuracy, the operator should not
enter any off road parking as this
would deviate from a straight mile or
kilometer measurement. At the end of
the measured mile or kilometer the
operator must press and release the
push-button one more time,
the display will show "CALCInG"
(Calculating)
while the microprocessor calculates
the numbers it needs and will restart.
The new pulses per mile or kilometer
will now be in effect. This feature may
be abandoned at anytime by pressing
and holding the push-button for two
seconds. The microprocessor will
reset itself and continue normal
operations. This menu item may also
be stopped by turning off power to the
speedometer.
The fourth menu item "SELF L " (Self
calibrate low axle) is used to
automatically calculate the pulses per
mile or kilometer for the low ratio axle.
The implementation and setting are
the same as number 3 "SELF HI"
above.
The last feature "donE" is used to exit
from this menu. If this display is left on
for 4 seconds and the push-button is
not pressed, the microprocessor will
return to normal operation with
nothing changed.
-10-

BOOT MENU
The Boot menu is for accessing set-
up information when programming the
functions of the speedometer. While
this information can be changed at
any time, placing it within the boot
menu prevents any accidental
resetting of this information. To access
the boot menu, press the pushbutton
while turning on the ignition. "HELLO"
will be shown on the odometer
window indicating that you have
entered the boot menu.
When the push-button is released the
first item on the menu will be shown.
In four seconds the microprocessor
will activate that menu feature. If you
want a different item from the menu,
you must press and release the push-
button before four seconds have
elapsed. The menu items will scroll
continuously. If you want to get out at
this point with no changes, stop at the
last menu item "donE", and in four
seconds the microprocessor will
return to normal with nothing being
changed.
If you are in a menu, just do nothing
for 32 seconds and the
microprocessor will restart and
change nothing.
The first menu item "SEr HrS"
(Service Hours) is used to set the next
service interval in hours.
This function is more applicable to
commercial and marine applications,
the next menu item, service distance
is better for vehicles that spend most
if the time driving rather than idling.
The second menu item "Ser
diS"(Service distance) will allow you
to program the mileage service
interval.
When this menu feature is started, the
display will show the actual miles
before the next service interval that
has been programmed will occur.
Starting at the leftmost digit, the digits
will flash on and off for four seconds.
During this time you may change the
digit by pressing and releasing the
push-button.
Once you have changed the digit
once you may push and hold the
push-button to have that digit count
continuously from 0 to 9. When you
have made your digit choice, don't
touch the push-button for four
seconds and the next digit to the right
will now flash and be accessible for
change.
-11-

This will continue for all the digits and
will go back to the first digit and
repeat. If the push-button is not
pressed for 32 seconds the
microprocessor will return to normal
and will change nothing. This is useful
if you're only here to check when the
present service interval will occur. The
operator may also turn power off at
this point and nothing will change in
the microprocessor controller. To save
the changes you have made in the
display, you must press and hold the
pushbutton while any digit is flashing.
The third menu item "Clr HrS" (Clear
Hour Service) allows you to clear the
hour service flag and automatically
reset the next hour service.
The fourth menu item "Clr diS" (Clear
distance) allows you to reset the
mileage service interval.
The fifth menu item "PPgn Hi"
(Program High axle) will allow the
operator to enter the pulses per mile
or kilometer for the high axle. This is
useful when you already know the
proper PPM or when some additional
fine tuning is needed.
This number will depend on how your
particular sender is arranged. The
maximum pulses per mile or kilometer
are limited to 150,000. When you stop
at the "PPn HI" display and wait four
seconds the microprocessor will
display six digits with the leftmost digit
flashing.
The number displayed will be the
present pulses per mile or kilometer
rounded off to the nearest 100 th. The
rightmost digit will be a "P" to remind
the operator that they are in the
"Programming" mode. The digit
changes and inputs are the same as
number 1 (Service Hours) above. Also
present is the same option to do
nothing for 32 seconds and the
microprocessor will reset itself and will
change nothing.
Holding the push-button on for four
seconds while a digit is flashing will
make the microprocessor compute the
observation window and will store this
window and the pulses per mile or
kilometer rounded off to the nearest
100 pulses in the microprocessor. The
display will now show "donE" and the
operator should release the push-
button to resume normal operations.
The sixth menu feature "PPgn LO"
(Program Low axle) is used to
program the low speed axle pulses
per mile or kilometer. The
implementation and activation are the
same as number 5 (Program High
axle) above.
-12-

The next item in the menu is the input
level control for the speed pulse
input. The display will show " InPuT ".
If nothing is done for 4 seconds then
the display will change to "L n H" and
the L will be flashing and every 4
seconds the next letter will flash.
If the button is pressed when any
selection is flashing, that input signal
level will be set to that level. The
choices are low, normal and High.
Low is normally used for magnetic
and hall effect senders and normal
and high for other types. This
essentially selects the sensitivity of
the speedometer. The speedometer
is preset at the factory at Low, if for
any reason a weak signal is
suspected (erratic pointer movement,
etc) try normal and high.
The last menu item "donE" is used to
exit from this menu. Leaving the
display in "donE" for four
seconds will cause the
microprocessor to go back to normal
SPEEDOMETER SENDING UNIT
INFORMATION
There are three types of speedometer
senders (or signal generators) in
general use in all electronic
speedometers. Hell effect, magnetic
and optical.
Your New Vintage Kit was supplied
with a hall effect speedometer sender.
This type of sender generates a signal
with both positive and negative pulses
from the unit (square wave). All hall
effect senders have 3 wires, positive,
negaitve and a signal, generally these
are red, black and white, with white
being the signal. A This type of sender
generally produces a cleaner signal
with less variance than the other types.
New Vintage speedometers will work
with ANY type, but we prefer to use the
hall effect style.
Magnetic and optical senders
(sometimes called a pulse
generator)use a negative signal that is
basically a on-off-on-off pulse. Many
OEM transmissions have these
installed from the factory and will work
fine with New Vintage speedometers.
This type of sender is identified by 2
wires coming from it, usually a black,
and a black/white. When using this
type of sender, please wire it into the
speedometer based on the provided
diagram onder optical/magnetic

GENERAL GAUGE TROUBLESHOOTING
Before you call, please check these items, they are sometimes obvious, but in the large
scope of a build, sometimes can be missed.
Double check grounds! Instruments operate on resistance to grounds. The connections
should be secure, soldered if possible. Remember, no Teflon or sealant on senders.
Senders have a tapered pipe thread and do not require sealant.
Double check with the wiring diagrams. There are a lot of wires to hook up to a gauge
set.
GENERAL
Gauge "sticks"
Loosen nuts that attach the back clamps. This can sometimes pull on the housing
enough to distort the dial and contact the pointer.
Gauge inoperative/reading incorrectly
Check for 12V at the gauge on the + and ground. Check for the correct resistance on the
sender
With power on, temporarily ground the sender lead, this will peg the gauge to its highest
reading.
TACHOMETER TROUBLESHOOTING
Erratic reading:
This is caused 99% of the time by a loose connection. Check spade or ring connectors.
Sometimes these are connected well enough to work for a while, but do not hold up.
Dead tach
Caused by no power, or no signal. Check for power. Turn on ignition and watch the
pointer, it should "jump"
Reads too high/low:
Usually this is caused by the incorrect # of cylinders on the back of the gauge. When
using a magneto or alternator to drive the tach, an adjustment pot. Is behind the label at
the 8:00 position on the rear of the gauge.
SPEEDOMETER TROUBLESHOOTING
Speedometer problems are very similar to tachometer issues. Check the obvious first,
grounds, power, correct connections. What type of sender are you using? Check for
pointer "jump" These refer to all speedometer problems from dead to will not calibrate.
Most speedometer problems can be traced to a problem with the signal to the gauge.
Hall effect sender test:
With the speedometer and sender wired up (sender removed from transmission) turn on
ignition and slowly rotate the sender shaft. You should get a signal of 10V+ then 10V-,
etc… If this is not the case, you may have a loose connection.
Another avenue to try is changing the signal input from L to N or H. This procedure is
described under the BOOT MENU section of this booklet. This is also a good way to
remedy a "floating" pointer. When a pointer kind of roams but is not steady. This is
usually from a weak signal to the speedometer.
Another option is to directly ground the sender and apply a switched 12V+ source to the
positive input side of the sender.
