Additional Information:
Wires:
Orange: Stage 1 solenoid output (ground type output) - single wire in single cavity connector
Red: +12 volt switched input (device power)
Black: Battery ground
Purple: Timer or shift light output (to relay or low current LED shift light, 0.25 amp MAX)
White: Tachometer signal input
Yellow: WOT micro-switch or TPS signal input
Orange: Clutch/trans-brake switch input (+12 volt when on)
Green: Stage 2 solenoid output (ground type output) - single wire in single cavity connector
Battery Ground: The best place to connect the Black, 16 gauge wire is directly to the battery negative
terminal. If this is NOT possible then the connection should be to the frame. There MUST be a quality, large
diameter ground cable going from the battery negative terminal to the frame if the frame connection
method is used. This is critical because the MS-001 is providing the ground path for the solenoid current via
this wire.
TPS Signal Connection: The installer must determine the proper wire to obtain the throttle position signal.
If a wiring diagram is not available a volt meter can be used to locate the proper wire.
1—Locate the throttle position sensor wires.
2—Connect the negative lead of the voltmeter to a good ground.
3—With key on probe the wires with the voltmeter, there should be a signal ground (will read 0.0 or close to
0.0 volts), a signal reference voltage (typically 4.90 to 5.00 volts), and the signal wire. The voltage on the
signal wire will sweep when the throttle is moved. The wire with the changing voltage is the signal wire. The
voltage may be rising or falling.
4—Insure that there is a voltage change of at least 2.50 volts when moving the throttle from the closed
position to wide open position. If there is not at least a 2.50 volt span then the TPS signal cannot be used to
trigger the activation input.
5—You can record the closed and wide open throttle voltages to manually enter into the setup parameters or
use Live Data mode as outlined in the programming instructions.
NOTE: If the MS-001 is connected to a TPS signal wire then the MS-001 MUST be powered up and configured
for TPS activation whenever the vehicle/engine controller is powered up, even if the nitrous system is not
activated. Otherwise it will interfere/offset the TPS signal. This is especially critical in electronic throttle
applications.
Tach (RPM) Input Signal: The tachometer input signal can be connected to the coil negative terminal or a
dedicated square wave signal from the ECM or other source.
Some ECM applications do NOT have a dedicated tachometer signal by default and may be turned ON using
aftermarket programming solutions. These ECM’s generally do NOT provide a pull-up resistor internally and a
4.7 k-ohm, 1/4 watt resistor will need to be connected from +12V to the tachometer signal wire.
