Overview

These new installation instructions are to be used with Version 2.1 of the WOT Box software. All WOT Boxes shipped after 6/17/08 will include this software. If you have an older WOT Box, you can upgrade the software on your WOT Box using by visiting the page: WOT Box Software.

Warnings:

• Don't 2-step for too long! Keep it under about 5 seconds. It will heat up your cat and potentially cause it to fail if you do it for too long or too often. It is only meant for use for a few seconds before launching. These warnings are the same for any 2-step.
• If the 2-step doesn't sound right, stop and contact us.

Installation Instructions - SRT-4

NOTE: If you have a CDI (capacitive discharge ignition system) please contact us at support@n2mb.com  for 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 technique 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.

1. Remove the battery. Not only is it a good idea to have the battery wires disconnected while working on your car, it will make accessing the wires you need to tap much easier.
2. Pick out a location to mount the WOT Box. We recommend inside the fuse access panel on the driver's side dashboard or any other convenient location under the dash. The WOT Box must be installed inside the passenger compartment since it is not waterproof.
3. Bundle the 16 AWG RED/BLACK wire pair with the long YELLOW and BLUE wires.
4. Route these wires through an available firewall grommet from the passenger compartment to the engine bay.
5. Locate the C101 connector. It is near the brake master cylinder on the firewall.

   

6. Run the 16 AWG RED/BLACK wire pair to the C101 connector, the BLUE wire to the TPS Sensor and the YELLOW wire to CAM Position Sensor. Be sure to run the wires away from heat sources and sharp objects that could damage them.
7. Disconnect the black C101 connector by sliding the red connector lock to the right. Then squeeze on the tab at the bottom of the connector and pull up on the top half. Once disconnected, unwrap the electrical tape from the corrugated plastic tubing and expose the wiring harness as shown.
   

   
   

8. Locate the DARK GREEN / ORANGE wire. Cut this wire about 2" from the C101 connector. Strip the two ends of this wire.
9. Split apart about 6" of the 16 AWG RED / BLACK wire. Strip the ends of the wire and slide two pieces of provided heat shrink tubing over the wires.
   

   
   

10. Connect the 16 AWG RED wire to the side of the DARK GREEN / ORANGE wire that is going towards the connector. Connect the 16 AWG BLACK wire to the side of the DARK GREEN / ORANGE wire that is going away from the connector as shown.
    

    

11. Solder the connections.
    

    

12. Cover the connections with the provided heat shrink tubing and heat the heat shrink with a heat gun.

    

13. Tape up the wiring harness and recover it with the corrugated tubing. Reconnect the C101 connector.
    
14. Locate the Cam Position Sensor. It is on the driver's side of the cylinder head. Locate the TAN / YELLOW wire of the Cam Position Sensor. It is connected to Pin 3 of the connector.
15. Peel back some of the insulation on this wire. Be sure not to break the wire. Strip the 18 AWG YELLOW wire from the WOT Box and wrap it around the TAN / YELLOW of the Cam Position Sensor. Solder this connection and wrap it securely with electrical tape. The connection should look as shown here:
    

    

16. Locate the ORANGE / DARK BLUE wire of the TPS sensor. It is connected to Pin 2 of the connector.
17. Peel back some of the insulation on this wire. Be sure not to break the wire. Strip the 18 AWG BLUE wire from the WOT Box and wrap it around the ORANGE / DARK BLUE wire of the TPS sensor. Solder this connection and wrap it securely with electrical tape.
18. This completes the under hood part of the installation. Move back into the passenger compartment.
19. Locate the clutch upstop switch connector. It can be found behind the clutch pedal, attached to the firewall. Locate the LIGHT GREEN / BLACK wire coming from this connector.
20. Peel back some of the insulation on this wire. Be sure not to break the wire. Strip the 18 AWG GREEN wire from the WOT Box and wrap it around the Clutch Upstop LIGHT GREEN / BLACK wire. Solder this connection and wrap it securely with electrical tape.
21. Lastly, using the provided ring terminal, connect the 18 AWG BLACK wire from the WOT Box to a good chasis ground. It is very important that the ground connection be clean and solidly connected. Problems will occur if this ground wire doesn't make a good electrical connection. Use sandpaper if needed to clean up the screw you use to connect to.
22. This completes the installation.

Troubleshooting

Testing the WOT Box

1. Key on the car but do not start the engine. Quickly 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 TPS signal connection.
2. The LED will go out in about 3-4 seconds because the computer will cut power to the WOT Box if the engine is not running. Turn the key off.
3. Turn the key back on and quickly press the gas to pedal to the floor. You should see the LED on the WOT Box start to rapidly blink. As soon as you see that, 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 Switch signal connection.
4. If you are not able to complete this procedure before the power is cut off, just key off the car, key it back on and try again.
5. 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 recheck the ignition and fuel injector cut wires. Verify that the RED and BLACK 16 AWG are wired facing the proper way. If they are reversed, the ignition and fuel cut will not work.
6. 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 Cam Position Sensor connection.

Since the NDE TCS draws its power from the ignition coil power supply, you have to make sure the RED wire for the NDE TCS is moved to a location that does not get shut off, i.e. before the WOT Box, as shown on the following diagram.
