1. Disconnect the battery negative terminal.
2. Pick out a location to mount the WOT Box. 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.
3. Locate a harness pass‐through on the firewall accessible from the passenger compartment. Some of these are grommets that have enough room for extra wires to be passed through next to the existing harness. Some have a tightly fitting skirt that the harness passes through that does not allow for extra wires. If yours is the second, carefully poke a new hole in the skirt using a sharp object, such as a screwdriver. Be careful not to damage other wires already in the grommet, and make sure that the hole is only large enough for the red/black pair and yellow wire from the WOT box to pass through. If it is too large, water can leak in.
4. Bundle the WOT Box 18 AWG YELLOW and 16 AWG RED / BLACK paired wires using electrical tape. Using a coat hanger or other sharp object, pull the bundle through the grommet in the firewall.
5. Route the connector end of the wiring harness to the desired mounting point. Be careful to avoid sharp metal objects and pinch points. Leave enough of the harness in the passenger compartment to make the WOT Box easy to get to, but not an excessive amount.
6. Locate the ignition coil wiring harness, usually on the driver’s side of the cylinder head, near the cam shafts. Remove some of the split loom tubing and tape to expose the wires.
7. Locate the ignition coil power wire(s). Refer to the Table #1 below to identify the wire colors for your vehicle. If your vehicle has more than one ignition coil, either locate the splice point where the power wires from all of the ignition coils come together at one point, or cut into all of the ignition coil power wires. Cut the wire(s) and strip both ends of the wire(s) about 5/8″.
8. Split apart about 6″ of the 16 AWG RED / BLACK wire from the WOT Box. Strip the ends of the wires and slide two pieces of provided heat shrink tubing over the wires. Connect the 16 AWG RED wire from the WOT Box to the wire(s) previously stripped that are going away from the ignition coils. Connect the 16 AWG BLACK wire to the wire(s) previously stripped that are going towards the ignition coil(s). Solder the connection and use the provided heat shrink tubing to cover the connection. Tape up the harness with electrical tape. Recover the harness with the split loom tubing and wrap with electrical tape.
9. Locate the wire specified in Table #2. You may tap into this wire at the device itself or at the ECU, whichever option is more convenient for you. This wire doesn’t need to be interrupted, but rather a signal read from it. Solder the 18 AWG YELLOW wire from the WOT Box to this wire, ensuring that the original connectivity of the wire is maintained. If the original wire is cut and later rejoined to do this (preferred), use the included heat shrink tubing to seal the splice. If not, cover the solder joint with electrical tape.
10. Secure all of the under‐hood WOT Box wires using the provided zip ties. Be sure to route the wires away from heat sources and sharp objects that may damage them. This completes the under‐hood portion of the installation.
11. Back in the passenger compartment, locate the Accelerator Pedal Position Sensor. It is at the gas pedal. Disconnect the connector.
12. Locate the Accelerator Pedal Position Sensor #1 signal wire. Or if your car is not drive by wire, you will tap into the Throttle Position Sensor. You may tap into this wire at the accelerator pedal or throttle position sensor itself or at the ECU, whichever option is more convenient for you. Refer to Table #3 below to identify the wire colors for your vehicle. Once again, this wire doesn’t need to be interrupted, but merely “tapped into.” Solder the 18 AWG BLUE wire from the WOT Box to this wire, ensuring the original connectivity of the wire. If the original wire is cut and later rejoined to do this (preferred), use the included heat shrink tubing to seal the splice. If not, cover the solder joint with electrical tape.
