IMPORTANT - The Nitrous and Fuel Solenoid
Grounds can be combined on either Output. This
will generally richen the mixture slightly due to the
Fuel Solenoid going to 100% sooner. This happens
because of the large EMF Voltage produced by the
higher amperage Nitrous Solenoid affecting the Fuel
Solenoid Operation.

Note - The Red LED lamp should
be on steady with Arming Switch
ON and the Activation Signal OFF.
LED Lamp will blink when +12V is
applied to the Activation Terminal.
Note - The activation terminal has an
integrated resistor to Ground. This is to
insure that the Timing Retard Inputs of
popular Ignitions are OFF when the
Controller is NOT activated.
