Sensor Location reference picture:

Step 1: Disconnect the battery Step 2: Locate the section of cable labeled "MAP" from the ProTuner main harness. Disconnect the factory MAP sensor plug, and connect the Pro-Tuner MAP sensor cable.

Step 3: Locate the CRANK sensor underneath the factory charge pipe. Find the Y-cable labeled as "CRANK" from the Pro-Tuner box. Disconnect the factory CRANK sensor cable, and connect the Pro-Tuner CRANK sensor cable on each end of the factory plugs. Locate the matching plug from the Pro-Tuner main harness and connect the other end of the crank cable.

Note: The Crank sensor is underneath the factory charge pipe. You can remove the factory airbox to access it.

Step 4: Locate the section of cable labeled "BOOST" from the ProTuner main harness. Disconnect the factory BOOST sensor plug, and connect the Pro-Tuner BOOST sensor cable on each end of the factory cable. *Note: The BOOST map sensor is located on the pipe before the throttle body, and it looks just like the Map sensor you connected on the Step 2.

Note: The BOOST sensor is located on the cold pipe just before the throttle body Step 5: Locate the CANbus cable from the Pro-Tuner and connect it to the CANbus port located next to the engine by the passenger side. Use electrical tapes to secure the connection. *If you do not have the CANbus(diagnostic port), it should have come with the in-cabin OBD-II connector. Please feed the wire through the driver side grommet and connect the provided OBD-II cable.

Step 6: Locate the Bluetooth Module from the Pro-Tuner box, and connect it to the matching plug on the Pro-Tuner harness.

Step 7: Optional Speed Limiter Canceler(Green Wires) - Coming Soon

Step 8: Use electrical tapes on each end of the Blue & Green wires as they are not used.

Step 9: Locate and connect the power wire from the Pro-Tuner to terminal location inside the fuse box.

Step 10: Connect the main harness to the Pro-Tuner ECU. Use Velcro fastener to mount the Pro-Tuner ECU & Bluetooth module on the desired location under the engine bay. Mount the Pro-Tuner ECU away from hood gaps to avoid water infiltration. *If you are washing the vehicle, please secure the harness & Pro-Tuner ECU from getting wet. Water damage is not covered under warranty.

Step 11: The 2 Pin Gray connector is for the V2 ICM (Water Meth Injection System) & 4 pin white connector is for developer firmware update cable. Use electrical tape to seal them as they are not being used. The V2 Meth Injection system can be purchased @https://www.lap3usa.com/product-page/pro-tuner-v2-meth-injection-kit

Step 12: Connect the Battery

Step 13: Check the Manufacture date stamped behind the Pro-Tuner ECU. Grab your Android device, install the following PROSS app from Google Play store based on the manufacture date. (*V1 does not have any manufacture date listed on the back)
