Wideband Installation

I.                    On the left side of the passenger foot well, locate the plastic kick panel plate. This plate is held in by white plastic clips. In order to remove the plate, simply pull towards the passenger side of the car.

II.                 With the plate removed, the carpet can be pulled back towards the rear of the car, in order to expose the grommet which the sensor will be pushed through.

III.               Remove the grommet by pulling on the edges your fingers.

IV.              With the grommet removed from the car, cut a slit down the middle of the grommet in order to fit the sensor through.

V.                 Reinstall the grommet with the sensor on the outside of the car, and the sensor plug on the inside of the car.

VI.              Unscrew the shift knob and remove the ashtray by sliding it up, and towards the back of the car.

VII.            Pull off the top piece of the center console, which is held in by 4 friction fit tabs. To remove the top piece of the console, simply pull it upwards.

VIII.         There will be 2 wires with blade connectors on the cigarette lighter, a light for the ashtray, and a light for the cigarette lighter. Both lights are removed by twisting 90 degrees at the base. The two blade connectors are pulled straight off of the cigarette lighter.

IX.              Locate the white connector with the brown wire. At this point you can either just tap into that power wire by stripping back some of the insulation, and wrapping another wire around it, and soldering the connection. Or, if you don’t want to touch any of your factory wiring, you can make a small patch harness with two blade connectors, and some wire. Pictured below is the patch I made. It simply uses a male and a female .187 slide connectors.

X.                 Continuing with the patch install, remove the white cover on the connector, using a small screw driver to pop up the tab on the bottom. Then, use the screw driver to push up on locking tab, on the top in order to release the entire pin.

XI.              With the pin removed, slide the power splice into place. Then tape around the exposed metal from the factory wire, in order to prevent contact from its surroundings. The picture below is of it un-taped.

XII.            Slide the other end of the splice back onto the slider on the cigarette lighter, and run the red wire down towards the kick panel removed in step one of this section. With red wire fed down to the kick panel and the lights, and power and ground to the cigarette lighter in place, reinstall the top of the center console.

XIII.         Leave the red wire on the ground, for wiring later in the instructions.

Wideband and Knock Buffer Wiring

I.                    If you used the purple wire for updating, remove the Purple wire, and using the same process as before, move the purple wire back into the pin that it originally came from. (Pin 10 on the gray connector)

II.                 Before placing the orange locking piece back into the bottom of gray connector, place the yellow pin of the knock buffer into pin 9 on the gray connector.

III.               Place the locking mechanism into the bottom of the connector, but leave the connector disconnected from the xede.

IV.              Now comes the wiring. Start by locating the brown wire on the wideband harness. Connect this wire to the purple wire going into the xede.

V.                 The grounds for the LC-1 wideband are Green, white, and blue. The ground for the knock buffer is black. Combine all of these grounds. Also include the black side of the LED supplied with the LC-1 kit in this group of wires.

VI.              Strip off a small piece of insulation on the xede ground, which bolts to the ECU. This ground will be solid black.

VII.            Connect the grounds from the wideband and knock buffer to the xede ground.

VIII.         The power for knock buffer board will be red, this wire to the xede power. This was the wire stripped in step VIII of the firmware section.

IX.           As for the Red power wire on the wideband harness, connect that to the wire that came from the cigarette lighter.

X.            The only remaining wires should now be, black and yellow on the wideband, and pink on the knock buffer.

XI.            Tap the pink wire to the pink knock wire on the xede harness. This wire will be in pin 4 of the black connector.

 

XII.            The black wire on the wideband is the calibration wire, and the yellow wire is an un-used output wire. Connect one side of the momentary calibration push button to this black wire, as well as the red side of the LED. The wiring is complete. Please note that the other side of the calibration switch is disconnected to protect against an accidental calibration while driving.
