Installation of the NCC-002 Nitrous Control Center 30
3.1.10 Connecting the NCC-002 to Throttle Position Sensors on Mechanical and Electrical
Throttle Vehicles
The NCC-002 is able to be connected to the Original Equipment Manufacturer (OEM) Throttle Position Sensor
(TPS) signal on both mechanical and electronic throttle vehicles. The NCC-002 can also be connected to the
Accelerator Pedal Position (APP) signal on most electronic throttle vehicles. The NCC-002 can be connected to
a rising or falling 5 volt signal. On most electronic throttles, both a rising and falling signal exists, and the
TPS
Setup Menu allows you to program the NCC-002 accordingly.
On electronic throttle applications, LPE generally recommends connecting to the rising voltage signal on the
throttle. One reason for using the TPS signal instead of the APP signal is that the throttle can be at a different
angle than what the APP is requesting. As an example, during a full throttle shift, the throttle may close despite
the accelerator pedal being fully applied.
In some applications, you may want to install a separate TPS to be connected to the NCC-002.
WARNING: It is very important to maintain the proper sensor signals to the ECM in electronic throttle
(also known as "Drive by wire") applications. The ECM closely monitors these signals for safety
reasons. Improper wiring could result in a reduced engine power condition, diagnostic codes, or even
loss of vehicle control.
NOTE: The wire colors and pin positions in the following wiring diagrams may differ from the wiring in
your vehicle. Identify the wires of the throttle body sensor harness in your vehicle and confirm their
individual functions before beginning one of the modifications below.
