ELITE SERIES ELECTRIC SPEEDOMETER
2650-1447-00
This electronic speedometer utilizes a single LCD to display odometer and two trip odometer mileages. Press the Trip/
Reset button on the dial window to cycle between odometer, Trip 1 and Trip 2 displays on the LCD. Pressing and holding
the Trip/Reset button for more than 2 seconds while viewing either Trip display will reset the current trip being displayed. The
odometer cannot be reset.
The speedometer is designed to operate with an electrical speed
sender. The speed senders signal pulse range must be between
500 and 400,000 pulses/mile. Any speed sender or electronic
module that meets the following two conditions can be used:
• Pulse range generated proportional to the vehicle speed
• Output within the voltage ranges listed below:
2.0 to 16V peak (Square Wave), 3 wire
2.0 to 120V peak to peak (Sine Wave), 2 wire
WARNING
Incorrect hookup will damage the speedometer and
void warranty. Please read these instructions carefully.
Mounting
1. Mount the speedometer in a 3
3
⁄8" dia. hole in the dashboard.
(be careful not to make the hole too large.)
2. Cut a
3
⁄8" dia. hole in the firewall for the speedometer wires. Place
a rubber grommet in the hole and route the connector wires through
the grommet to the engine compartment.
3. Connect the speedometer wires as shown in the wiring section.
4. Secure the speedometer to the dashboard using the provided
bracket and hardware.
Note: With the ignition switch off, the speedometer pointer may not
always rest at zero. This is normal. When engine is started, the
pointer will first move to half scale then will rest at zero.

Speedometer Senders
NOTE: The odometer on this speedometer may read from 1 to
5 miles. This is done during factory testing to ensure
optimum quality.
Recommended Auto Meter Hall-Effect (Square Wave),
3 wire, 16 Pulses Per Revolution senders:
5291 Standard 7/8-18 thread
5292 Ford, plug in
CAUTION!
As a safety precaution, the power wire to this product should be
fused before connecting it to the positive (+) side of the 12 VDC
battery. We recommend using a 1 AMP fuse.
Once the speedometer is mounted and wired into the vehicle, the
speedometer should be tested to verify the electrical connections
are working properly. First, watch the speedometer’s pointer as
the power is applied. The pointer should first move to a midrange
position, then down to the zero box on the dial. This action verifies
that power is properly connected to the speedometer. The vehicle
should be driven some distance to verify the Vehicles Speed
Sender (VSS) is connected properly, and that the pointer moves.
If the pointer does not move off the zero box, verify the VSS is
connected properly.

Calibration
To calibrate your electronic speedometer:
1. With the power off, push and hold the calibration button (trip/reset
button when equipped). While holding the button, start the vehicle
and continue to hold the button until the pointer sweeps to full
scale and stays at full scale. You may now release the button.
2. Drive to the beginning of a pre-marked 2 mile distance and
come to a stop. It does not matter how far away it is to get to this
pre-marked 2 mile distance. Do NOT shut the engine off. Push
and release the button. The pointer will drop to half scale.
3. Drive the 2 mile distance. The pointer will remain at the half scale
mark no matter what speed you drive. If the speedometer has a
LCD display odometer, it will be normal to see it counting
rapidly as it is receiving a speed signal. If you have to stop
during the calibration, that is o.k. The speedometer is simply
counting pulses during this time.
4. At the end of the 2 mile distance, come to a complete stop and
push and release the button. The pointer will drop to 0 and the
calibration is stored.
Remember the accuracy of your 2 mile distance will directly affect
the accuracy of your speedometer.
