Installation
1. Cut a hole in the dashboard for the location of the speedometer.
Check above for diameter dimensions for your speedometer.
2. To connect the speedometer cable:
A. If existing speedo cable in vehicle is being used, connect it
to the cable input on back of speedo. Make sure cable fits
properly into .104" sq. female cable input before tightening.
B. If a new speedo cable is required, purchase a “custom made” cable
from an auto parts store or speedometer specialty shop. The cable
input on back of speedometer accepts only .104" sq. male drive. Make
sure connections fit properly before tightening.
3. Drill a 11⁄16" diameter hole in engine firewall where cable will be
routed. Route cable from speedo through dash, through firewall and
connect to transmission take-off. Use the rubber grommet provided
(slit) to support the cable in the firewall. Make sure all connections fit
properly before tightening.
4. Secure the speedometer in the dashboard by using the brackets,
nuts and lock washers provided.
NOTE: The clear lens on your speedometer may be made of acrylic. To prevent scratching use a mild, soapy solution and soft cloth to clean. Wipe lightly.

5. For lighting connect the light wire to dash lighting circuit (or +12
volts). If speedometer is mounted in a non-metal dashboard, a
separate wire must be connected between one of the speedometer
case mounting studs and an engine ground (-neg.)
Specifications: This speedometer is set up for a 1:1 drive ratio (60
MPH at 1,000 RPM input to speedometer head) and a 5⁄8" x 18 threaded
cable input that requires a .104" sq. male drive. If vehicle tire size and/or
rear-end differential are not stock (original), a different driven gear in the
transmission may be required for speedo accuracy. If a change in the
driven gear is made, you very likely will have to change the drive gear in
the transmission to maintain the proper gear tooth engagement. Another
approach is to use a “correcting ratio” drive joint to adjust the speedometer
input to 60 MPH at 1,000 RPM. If one is needed, the appropriate ratio can
be easily determined by comparing your speedometer reading against
another car having an accurate speedometer and dividing the speeds.
(Accurate speed ÷ Your speed = Ratio needed) Auto parts stores or
speedometer specialty shops carry “correcting ratio” drive joints or contact
Auto Meter Products.
