Just got done putting the reverse override on my griz660. By using
a relay the reverse light and speed limiter work normally until
you push the override button and then the light goes off. Unplug
the green w/ white trace wire by the fuel shutoff, connect the
female side to term. 30 on the relay. Connect the male side to
term. 87A. Put fused and switched 12v power to term. 86. From one
side of thepushbutton go to term. 85. Now from the other side of
the pushbutton and term. 87 go to a chassis ground. When you push
the button you are in override, while testing mine I saw 46 mph
in reverse(on the stand).
