What makes the Traction Control Window Switch so unique?
• Lets you set when the nitrous comes on and when it shuts off, based on the engine’s rpm
• Traction control, Skip-Shift Technology lets you select what gear the nitrous will be activated
in
• Easily hooks up to a ZEX™ system or activates other nitrous systems using a standard
automotive relay
• Can be used to control a second stage of nitrous
• Adjustable up to 20,000 rpm
How the ZEX™ Traction Control Window Switch works:
The Traction Control Window Switch receives an rpm signal from the engine’s ignition. It accepts
most tach signals, including low-voltage and irregular signals, such as those found on many V10s.
Through programming, the user has total control at what rpm the nitrous comes on and shuts off.
Additional programming of the switch lets you select what gear in which the nitrous begins to spray. In
the case of a ZEX™ EFI nitrous system, the Traction Control Window Switch interrupts the TPS
signal going to the nitrous management unit. With a non-ZEX™ nitrous system, the Traction Control
Window Switch can control a standard automotive relay, connected to the non-ZEX™ system’s

How Skip-Shift Technology works:
One of the most unique features of the ZEX™ Traction Control Window Switch is its Skip-Shift
Technology. The Skip-Shift feature allows you to select what gear the nitrous begins to spray in. This
feature is especially beneficial to vehicles with street tires that would normally have traction issues if
nitrous were sprayed in first gear, or in some instances, even second gear. Skip-Shift knows what gear
you are in by watching the number of times your deactivation rpm point has been passed. For example,
if the window switch’s deactivation rpm is set at 6000 rpm, you need to ensure that you pass that rpm
point before you shift the vehicle. In other words, if you enter a “2” into the Traction Control Skip-
Shift menu, you will have to pass 6000 rpm twice before the nitrous will begin to spray. To reset the
Skip-Shift feature after a run, simply turn off the power to the switch, and turn it back on again.
WARNING!!!!
The white output lines are normally an open circuit (current cannot pass), but when the switch is
activated, they become a closed circuit (current can pass). This circuit is rated at a maximum current of
0.5 amps, so attempting to control any device that draws greater than 0.5 amps will cause damage to
the circuits of the switch. The Traction Control Window Switch requires 9–18 volts to operate
correctly.
Display Functions While In Run Mode:
• Number display A, B, and C – The three digit display shows the engine’s rpm x 100 (i.e. 045
= 4500 rpm)
• Active Indicator Light – When illuminated, the switch is in-between the rpm set points and is
activating the nitrous system
• Lockout Indicator Light – When illuminated, the unit is waiting for the vehicle to pass
through a gear before spraying nitrous
Switch & Display Functions While Programming:
Button #1 – Toggles through the configuration menu
Button #2 – Increments the flashing value that is selected
Number A – Displays the current step in the programming process
Number B – Value for the current configuration step
Number C – Value for the current configuration step
