Mounting 

Remove the speedometer cup from the handle bars.  Remove the screw on the bottom of the cup to separate the 

front ring from the cup.  Unplug the factory 3-pin harness.  Remove the two nuts from the back of the speedometer to 
release it from the front ring.  Install the new speedometer into the front ring and use the original clamp and the supplied 
thumb nuts to secure it.  Connect factory 3-pin harness into the new speedometer.  Reinstall the front ring into the cup and 
replace the screw into the bottom of the cup.  Reinstall the cup onto the handle bars. 

 

 

 

Note: On some models with tank mounted speedometer it may be necessary to trim the mounting studs on the back of the 
gauge for proper clearance and fit.   

 

Wiring 

The three pin plug on the back of the gauge mates into the factory speedometer wiring harness. Simply unplug the 

stock gauge and plug in the new Dakota Digital BD-140.
