• NOTE: If you have a CDI (capacitive discharge ignition system) please contact us at support@n2mb.comfor additional instructions. Damage to your WOT Box can occur if the installation is not completed correctly!

  WARNING: Spark-based rev-limiters can damage catalytic converters.If you have catalytic converters on your car, N2MB accepts no responsibility for damage caused by the WOT Box.This being said, many successful installs have been made on Catalytic-Converter equipped vehicles.Damage usually is only caused by using the launch-control feature for more than a few seconds, but once again, USE AT YOUR OWN RISK IF YOU HAVE CATALYTIC CONVERTERS!

  
  

  Solder all joints.The N2MB recommended soldering method is available here.Use a multimeter to verify all wires before they are cut or tapped into.The colors of wires from model year to model year may differ, and may be different on your car from those described in these instructions.Where discrepancies are known, they are described, but there may be more discrepancies than those listed.The best way to know that you have the right wire is to check the connectivity to the ECU and/or sensor at the pins described.

  In these instructions, pictures include other aftermarket alterations in addition to the WOT Box.N2MB is not affiliated with these devices.In addition, if you see something that isn’t in your vehicle, don’t worry.

  Route wires in the manner that you want them to lie permanently before connecting them.  Cut wires to length before soldering; avoid coiling wires of excessive length as they can cause noise in the circuit, altering the operation of the WOT Box.  Spending some extra time here will enhance the aesthetics of the install.  Zip ties are included to secure the wires away from heat, moving parts, sharp edges, or anything else that can damage the wires.

• Disconnect the battery negative terminal

• Pick out a location to mount the WOT Box. We recommend the small pull-out tray on the drivers side of the dash, to the left the steering wheel. The WOT Box must be installed inside the passenger compartment since it is not waterproof. Additionally, you will want to make the WOT Box accessible to the driver, due to the fact that setting the 2-step RPM will require holding down the clutch pedal while holding the button on the WOT Box.

• Locate the rubber grommet on the drivers side firewall. Using a coat hanger or other object, poke a hole in the grommet. It helps if you use something to poke the hole and then enlarge it (like a screw driver) before trying to shove all the wires through. Be careful not to damage the wiring harness that is already there. To make it a little easier, get a spray bottle with a solution of mildly soapy water. Spray the boot as you are pulling the harness through and it should come through with ease.

• Bundle all the WOT Box wires EXCEPT the 18 AWG BLACK wire and pull them through the grommet. Use minimal force when pulling the wires through so that you don't pull the grommet out of the firewall.

• Leave enough of the harness in the passenger compartment to make the WOT Box easy to get to, but not an excessive amount. Route the harness to the pull-out tray.
  

• Important: Secure the harness using the provided zip ties. If the harness is not properly secured, it may interfere with the operation of the vehicle pedals, causing an unsafe condition. Always secure all wires and route them away from sharp or moving objects that may damage them.
  

• Feed the harness through to the pull-out tray.
  

• Now, under the hood, locate the following connector on the driver's side of the cylinder head. It is an 8-pin connector with 7-wires. It provides power, ground and the control signals for the ignition coils. Unplug the connector.
  

• Unwrap the electrical tape on the harness and expose the wires from the split loom tubing.
  

• For the following two wires, the colors may vary from year to year. However, the wires you must tap on the coil pack harness are the top left most and top right most wires, where the top of the plug is defined as the plug side with the lock piece on it.
  
• Locate the DARK BLUE / WHITE wire (EST B Control) and carefully strip back some of its insulation. Be sure not to break the wire.

• Locate the PINK / WHITE wire (ignition coil power). Cut the wire and strip it back about 5/8".

• On the 2005 year cars, your harness may look as follows:
  

  
  
  

• Split apart about 6" of the 16 AWG RED / BLACK wire from the WOT Box. Strip the ends of the wire and slide two pieces of provided heat shrink tubing over the wires.

• Connect the 16 AWG RED wire to the side of the PINK / WHITE wire that is going away from the connector. Connect the 16 AWG BLACK wire to the side of the PINK / WHITE wire that is going towards the connector as shown. 

• Solder the connection.

• Use the provided heat shrink tubing to cover the connection. Heat the heat shrink with a heat gun to seal the connections.

• Connect the 18 AWG YELLOW wire from the WOT Box to the DARK BLUE / WHITE wire (EST B Control).

• Solder the connection.
  

• Cover the connection with electrical tape.
  

• Tape up the harness and reconnect the connector.

• Locate the C1 connector on the Powertrain Control Module. The connector is a BLUE 56-Way F Micro Sealed connector. More information about the connector is available here:
  http://cobaltss.net/resources/pcm/05cobalt20.htm
• Locate the DARK BLUE wire coming from pin 27 (Accelerator Pedal Position Signal #1) and carefully strip back some of its insulation. Be sure not to break the wire. 
• Unfortunately, there are two DARK BLUE wires in this connector, so you can either attempt to tell them apart based on their position in the connector, or guess and check with a volt meter. If you connect a volt meter to the correct wire with the ignition on, it will vary between about 1 volt with the gas pedal up and about 4 volts with the pedal down. The other wire will have a constant signal.
  
• Connect the 18 AWG BLUE wire from the WOT Box to the  DARK BLUE (Accelerator Pedal Position Signal #1) wire. Solder the connection and cover with electrical tape. 
• For the 2005 M/Y Cars, the connections are unchanged: 

  

• Locate the BROWN / WHITE wire coming from pin 53 (Clutch Pedal Position Switch Signal) and carefully strip back some of its insulation. Be sure not to break the wire.
• Unfortunately, there are two BROWN / WHITE wires in this connector, so you can either attempt to tell them apart based on their position in the connector, or guess and check with a volt meter. If you connect a volt meter to the correct wire with the ignition on, it will show 12 volts with the clutch pedal up and 0 volts with the clutch pedal down.
• Connect the 18 AWG GREEN wire from the WOT Box to the BROWN / WHITE (Clutch Pedal Position Switch Signal) wire. Solder the connection and cover with electrical tape.
• The BROWN / WHITE wire is shown below.

• This completes the engine compartment portion of the installation. Secure any wires, replace any covers and remove any tools left behind from the engine bay.
• Back in the passenger compartment, locate the following ground connection under the dash.
  

• Using the provided ring terminal, attach the 18 AWG BLACK wire from the WOT Box to this ground connection. You can cut the black wire to about 3', but be sure to leave enough wire so that the harness will have enough slack to make the WOT Box accessible in the once installed in its final location. Be sure to crimp the ring terminal connection solidly and solder if possible.
• The installation is complete.

Testing the WOT Box

1. Key on the car but do not start the engine. Press the gas pedal to the floor. You should see the LED on the WOT Box start to rapidly blink. If it does not, check your APP signal connection(WOT Box BLUE wire).
2. Next, with the gas pedal still fully depressed, press the clutch pedal to the floor. You should see the LED on the WOT Box briefly go out, and then come back on solid for one second and then finally resume blinking rapidly. If you do not see this, check your Clutch Pedal Position Switch signal connection (WOT Box GREEN wire).
3. Next, start the engine. Quickly press the gas pedal to the floor and immediately step on the clutch. You should hear the engine start to rev up, stumble for a short period while the ignition and fuel is cut, then return back on and continue rev'ing. Remove your foot from the gas before you hit the rev limiter. The 2-step will not engage if the gas is depressed before the clutch. This is normal. If the engine does not stumble or pause when the LED turns out, then check the WOT Box RED / BLACK paired wires. Verify that the RED and BLACK 16 AWG are wired facing the proper way. If they are reversed, the ignition cut will not work.
4. Lastly, test the 2-Step. Press the clutch pedal down and then press the gas pedal all the way down. The engine should rev up to the desired RPM and hold. If it does not, be sure to remove your foot from the gas before you hit the rev limiter. If the 2-step does not work, check the Ignition coil control signal (WOT Box YELLOW wire) 
   On the Cobalt SS and Ion Redline, the Cruise Control Clutch Switch fuse is labeled “Emisn Fuse” and is a 10 Amp fuse connected to pin C1.If the WOT Box doesn’t work and you determine that it isn’t getting a clutch signal, check this fuse in the underhood fuse block.
