4 inch Tachometer – Model 201004

The tachometer is installed directly to the right of the steering

column (see photo). Use only the installation components

provided with the gauge.
NOTE: This tachometer is calibrated to work with an eight

cylinder engine. This tachometer will work with most factory

and aftermarket ignitions except magnetos.
1. The light bulb assembly comes installed on the rear of the

gauge housing.

2. Attach lighting wires to the bulb leads. The white is (+)

positive and the black is (-) negative.

3. Using spade connectors, attach negative ground (neg.

ground), power (+12 vdc), and ignition signal (ignition) wires

to the back of the tachometer. The back of the tachometer

has male spade connectors with raised lettering in the

plastic case identifying each connection.

4. Hold the bracket up behind the dash and align the studs

of the gauge with the bracket. When the bracket is placed

over the gauge case studs, install a star lock washer and

thread a thumbnut onto each stud. As you tighten the

thumbnuts make sure the gauge is aligned properly.

5. Position all wires away from hazardous moving parts or hot

engine components.

4 inch Speedometer - Model 201005

The speedometer is installed to the far right of the steering

column under the three gauge cluster in the center of the car (see

photo). Use only the installation components provided with the

gauge.
NOTE: This speedometer is calibrated for 1,000 cable revolutions

per minute equal to 60 miles per hour.
1. The light bulb assembly comes installed on the rear gauge

housing.

2. Pull the speedometer cable through the mounting hole in the

dash. Attach the speedometer cable to the speedometer.

The threads on the back of the speedometer are 5/8 –18

thds.

3. Attach lighting wires through the gauge hole to the bulb

leads. The white is (+) positive and the black is (-) negative.

4. Hold the bracket up behind the dash and align the studs of

the gauge with the bracket. When the bracket is placed over

the gauge case studs, install a star lock washer and thread

a thumbnut onto each stud. As you tighten the thumbnuts

make sure the gauge is aligned properly.

5. Position the speedometer cable away from hazardous

moving parts or hot engine components to the point of

insertion on the transmission.

6. Ford Top Loader transmissions can have speedometer

drives on either side of the transmission. Additionally, the

speedometer drive can rotate in both directions depending on

the configuration. If the speedometer fails to indicate speed

when the car is driven, the speedometer cable is rotating

in the wrong direction. A speedometer cable reversing

adapter will be needed. CA Instruments® speedometer

cable reversing adapter (part # CAIBG241) will work in this

application.

7. Reconnect the battery and inspect installation for binding,

sharp turns in the cable.
