Important Information - You must use Static Suppression Ignition Wires with this controller. The
71900 Progressive Nitrous Controller contains high frequency digital electronics and will NOT function correctly
without suppression wires.
Warning -
Do not mount the progressive controller anywhere near ignition components or any other
source of electronic noise.
Notice - The controller must be grounded directly to the vehicle’s battery.
Caution - Do not submerge the controller in liquid or directly wash the unit with liquid of any type!
Warning - The programming switches are delicate electronic items and can be damaged by misuse
and/or carelessness. If the controller is close to your nitrous bottle, be careful when installing the bottle.
The weight of the bottle is enough to easily damage the switches. Switches that have been determined
to be damaged due to neglect will NOT be covered under warranty.
