Mounting

Can be mounted in a 3 5⁄32" dia. hole in the dashboard. (Take care that hole is not cut too large.) 
Can also be mounted in a standard aftermarket street rod panel.

Installation

1.  To connect the speedometer cable:
A.  If existing speedo cable in vehicle is being used, connect it to the cable

input on back of speedometer. 
Important:    Make sure cable fits properly into .104" sq. female cable 
        input before tightening or speedometer may be damaged.

B.  If a new speedo cable is required, purchase a “custom made” cable  
    from an auto parts store or speedometer specialty shop. If unable to  
    obtain a speedometer drive cable locally, contact Auto Meter at    
    address below. Indicate the size and type of cable end to fit in the    
    transmission speedometer drive, type of attachment to the    
    transmission and length of cable needed. The cable input on back of  
       speedometer accepts only .104” sq. male drive. Make sure    
    connections fit properly before tightening.

2.  Cut a 1

1

/6" 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 and that    
  the rotating cable is not too long or short for proper engagement    
  before tightening.

   SERVICE

For service send your product to Auto Meter in a well packed shipping carton. Please include a note explaining what the problem is along with your phone number. Please specify when you 
need the product back. If you need it back immediately mark the outside of the box “RUSH REPAIR,” and Auto Meter will service product within two days after receiving it. ($10.00 charge will be 
added to the cost of “RUSH REPAIR.”) If you are sending product back for Warranty adjustment, you must include a copy (or original) of your sales receipt from the place of purchase.

12 MONTH LIMITED WARRANTY

The manufacturer warrants to the consumer that this product will be free from defects in materials and workmanship for a period of twelve (12) months from the date of the original purchase. Products 
that fail within this 12 month warranty period will be repaired or replaced at the manufacturer’s option to the consumer, when determined by the manufacturer that the product failed because of defects 
in material or workmanship. This warranty is limited to the repair or replacement of parts in the instrument and the necessary labor done by the manufacturer to affect the repair or replacement of the 
instrument. In no event shall this warranty exceed the original purchase price of the instrument, nor shall the manufacturer be responsible for special, incidental or consequential damages or costs 
incurred due to failure of this product. Warranty claims to the manufacturer must be transportation prepaid and accompanied with dated proof of purchase. This warranty applies only to the original 
purchaser of product and is non-transferable. All implied warranties shall be limited in duration to the said 12 month warranty period. Breaking the instrument seal, improper use or installation, accident, 
water damage, abuse, unauthorized repairs or alterations voids this warranty. The manufacturer disclaims any liability for consequential damages due to breach of any written or implied warranty on all 
products made by the manufacturer.

3.  Secure the speedometer in the dashboard by using the bracket, thumb  
  nuts and star lockwashers provided.

4.  Install light in back of gauge and connect one wire to dash lighting circuit  
  or to other 12V source. Connect other wire to (-) negative ground.

Specifications:    This speedometer  is  set up  for  a  1:1  drive ratio  (60  MPH  at 
1,000 RPM input to speedometer head) and  a 
requires a .104

" sq. male drive. If vehicle tire size and/or rear-end differential are 

5

⁄8" x 18 threaded cable input that 

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 at the address or phone below.
