Description:
The CTAP-001 Clutch and Throttle Position Activation Switch Module provides window switch activation based on most
common 0-5 volt sensor signals. The CTAP-001 is designed to connect to 0 to 5 volt DC sensors including most throttle
position sensors (TPS), accelerator pedal position (APP) sensors, clutch pedal position (CPP) sensors, brake pedal position
sensors and manifold air pressure (MAP) sensors. The CTAP-001 will accept either a rising or falling voltage signal.
The primary uses for the CTAP-001 are:
• Control the activation of nitrous systems based on throttle position
• Control the activation of a 2-step based on clutch pedal position
In nitrous applications the CTAP is normally used to disable the nitrous below a specified throttle angle. The CTAP allows
you do to this on most EFI engines without having to add a wide open throttle (WOT) switch. This is especially helpful
on electronic throttle equipped vehicles where no mechanical throttle linkage exists to connect a microswitch to. The TPS
based enable is normally used in conjunction with an RPM based enable/disable strategy using a Window Switch or a
programmable nitrous controller with built in RPM limit capabilities.
For 2-step applications, the CTAP is used to enable the operation of the 2-step based on clutch pedal position in newer
vehicles that have a clutch pedal position sensor. Vehicles such as the 2010-2014 Camaro, 2008-2013 Corvette and the
2009-2014 Cadillac CTS-V are equipped with a clutch pedal position (CPP) sensor. Unlike the clutch pedal switches found
on many earlier vehicles, the CPP sensor behaves much like a throttle position sensor. This means that it does not provide
an open or closed type contact that can be used to directly enable or disable a 2-step, relay or other device. The CTAP
takes the variable voltage signal from the CPP sensor and provides a programmable switched output that can then be
used to enable and disable a 2-step or other device. This also gives the added benefit of making it very easy to adjust
where in the pedal travel the 2-step activates.
Note the CTAP is usually not needed with the LPE NCC-001 and NCC-002 nitrous controllers since these devices can
accept a throttle and/or clutch pedal position sensor signal directly.
WARNING: The CTAP-001 can not be connected to the throttle position sensor on the new GM direct
injection V8 and V6 engines or other engines that use a digital throttle position signal. This includes
the 2014+ C7 Corvette (LT1 or LT4) and the 2014+ 4.3L, 5.3L and 6.2L Sierra and Silverado trucks.
On these vehicles the throttle position signal is no longer a 0-5 volt signal but is a digital serial data
signal. Contact LPE for alternative methods of obtaining a TPS signal on these vehicles.

Notes
Red
+12 Vdc
Connects to a switched and fused +12 volt DC source.
Orange
Normally
Off +12 Vdc
Output
This is the normally open (OFF) +12 Vdc activation wire. This wire will close the
+12 Vdc path when the switch is activated. This connects to the +12 Vdc side
of the device you plan to control.
Black
Ground
Connects to a vehicle ground.
Purple
Analog Input
This connects to the analog signal output wire of a Clutch Pedal Position
sensor, Throttle Position Sensor, Accelerator Pedal Position sensor, or other
rising or falling 0-5 volts signal sensors.
Gray
Normally On
Ground Output
This is the normally closed (on) ground activation wire. This wire will open the
ground path when the switch is activated. This connects to the ground side of
the device you plan to control.
Yellow
Normally Off
Ground Output
This is the normally open (off) ground activation wire. This wire connects to
ground when switch is activated. This connects to the ground side of the device
you plan to activate.
