■Introduction
“Safety precautions” are described in the Instruction Manual. Please read them before starting the installation work. “Signal words and their meanings” are described in the Instruction Manual for this product. The “Engine Control Unit” is abbreviated as “ECU” in this document.
！ CAUTION ●Regarding the installation of this product, be sure that it is installed by an experienced professional. After completion of the installation, hand over this document, Instruction Manual, and Warranty to the customer (user).
●Do not pull the harness of the vehicle and the harness of this product, Wire breaking or a short circuit may occur, thereby giving damage to this product and the vehicle.
●When removing or connecting a connector, be sure to unlock the locked (claw) status beforehand. When the connector is provided with a fixing bolt, loosen this bolt completely before pulling out the connector. The connector may be damaged.
●Arrange the harness of this product and the harness of the vehicle in portions that are not at a high temperature or are not movable. Arrange them so that water may not be splashed over them. Wire breaking or a short circuit may occur, thereby giving damage to this product and the vehicle.
●Do not arrange the harness of this product and the harness of the vehicle near a sharp-edged material. Do not put the harness between materials by applying pressure to it. Wire breaking or a short circuit may occur, thereby giving damage to this product and the vehicle. 2
■Precaution on Installation ●When installing this product, do not use any electro-tap in any case. Using the electro-tap makes the contact status unstable. Its contact defect may causes a malfunction to the product and damage to this product and the vehicle. Be sure to use the attached splice and dedicated tools such as cutting pliers for electric work to install the product securely.
●Insulate the metallic portion of the harness securely with a vinyl tape. ●Caulking the plug (1) Peel off the coating of the wires about 8 mm
(2) Cover with a sleeve
(4) Caulk securely
(3) Fold the wires
※Check if caulking has been performed securely by referring to the following figure Caulk the conductors by these portions Make the caulking thrust into the wire Caulk the coating by these portions
●Caulking the splice
(1) Peel off the coating of the wires to be connected about 5 mm
(2) Peel off the wires to be branched about 10 mm
(3) Entwine the wires
(4) Caulk securely
※Insulate the caulked portion securely with a vinyl tape

●The ground conductor of this product has two branches (black and brown). This has a very important significance to secure the voltage conversion accuracy. Connect the ground conductor by referring to the following figure. Installing the ground conductor in a different way from the connecting method specified by A’PEX will give damage to this product and the mounted car engine.
Correct Connecting Method for the Ground Conductor Connect the ground conductor to two positions of the same line. Be sure to connect the brown wire to the ECU side. Allow a space of 1 cm or more between the connecting point of the black wire and the connecting point of the brown wire. Vehicle harness

■Installation ●Connecting the VAFC II １.Remove the negative (-) terminal of the battery. advice!
There is some setting data on car audio, car navigation, etc. that is backed up by battery power supply. We recommend you to take a note of the data beforehand lest they should be lost.
！ CAUTION ●Before starting the wiring work, remove the negative terminal of the battery. If not, a fire will be caused by short circuit, thereby giving damage to electric parts. If the ECU connector is removed while the battery is connected, the engine warning lamp may light up continuously regardless of whether the VAFC II is installed or not. At this time, you must ask the distributor of each car model to perform maintenance and inspection.
●We shall not take all responsibility for damage of the vehicle or related devices that may be caused by installation error. ２.Locate the Engine Control Unit (hereafter referred to as ECU) of the vehicle by referring to the Wiring Diagram by Model. ３.Connect the harness attached to the V-AFC II securely to the power cable of the vehicle harness, grounding conductor, engine revolution signal wire, throttle signal wire, and TDC signal wire, VTC signal wire, and VTM signal wire that are connected to the ECU, by referring to the Wiring Diagram by Model. (Refer to page 7.) Connect the red wire to the IG power. Connect the green wire to the engine revolution signal wire. Connect the gray wire to the throttle signal wire. Connect the black wire to the grounding conductor. Connect the brown wire to the grounding conductor. Connect the orange wire to the VTC cam signal wire ※ Connect the light blue wire to the TDC signal wire. ※ Connect the blue wire to the VTM signal wire. ※ ※The RDC signal wire and the TCC cam signal wire are limited to vehicles with an i-VTEC. ※The VTM signal wire is limited to vehicles with a V type engine and some car models. ※For the details of the above TDC signal, VTC cam signal, and VTM signal, refer to the terminal arrangement drawings on and after page 5
■Installation (cont.) ！ CAUTION ●Be sure to connect the black wire and the brown wire of the harness attached to the VAFC II to the ground conductor. This product may not function normally, thereby giving damage to the product and the engine.
●When locating each wire, take special care not to cause a short circuit. A fire may be caused or electric devices may be damaged.
●Install the splice for branching securely without any contact defect. A fire may be caused or electric devices may be damaged. ４.Cut the pressure signal wire or VTEC solenoid signal wire of the vehicle harness connected to the ECU and install a plug by referring to the Wiring Diagram by Model. For some applicable models, cut the VTM signal wire and install a plug. Pressure sensor signal

！ WARNING ●Install the V-AFC II so that it may not interfere with driving. Normal driving operations may be prevented, resulting in an accident.
●Do not install the V-AFC II in a high-temperature place or a place exposed to direct water. An electric shock or fire may be caused or electric parts may be damaged. A malfunction may be caused, thereby giving damage to the vehicle.
●When passing the connecting harness of the V-AFC II, arrange the harness so as not to touch the moving portion. The connecting harness may be cut or short-circuited. The V-AFC II will be damaged, thereby giving damage to the vehicle and electric parts.
●Checking after installation After installing the V-AFC II, check the following items once again. ・Check if the harness attached to the V-AFC II is securely connected. ・Check if the harness is not unnaturally arranged. ・Check if the V-AFC II is securely fixed. ・Check if the negative (-) terminal of the battery is securely connected.
●Turn on the ignition switch. (Do not start the engine in any case.) Check the following contents after turning on the ignition switch. ・Check if characters are correctly displayed on the display part of the V-AFC II. If the display of this product is not made correctly, stop using the product immediately and make contact with the distributor or your nearest A’PEX business office. ・Check if any abnormal noise or offensive small is produced from the V-AFC II and the vehicle. If any abnormal noise or offensive smell is sensed, stop using this product immediately and make contact with the distributor or your nearest A’PEX business office.
●Initial setup ・If no abnormality is found with the ignition switch ON, perform initial setup for the V-AFC II. ・ Perform sensor number setting, number-of-cylinders setting, VTEC type setting, throttle sensor voltage checking, throttle sensor type setting, and throttle opening learning according to “Initial Setup” on page 13 in the separate Instruction Manual. And set the reference cam angle for vehicles with an i-VTEC.
When the engine is ready to start after initial setup, the installation work is completed. 8
！ CAUTION ●Do not start the engine in any case before the initial setup is performed. If the engine is started without initial setup, the engine may be damaged. Set the corresponding items by referring to page 13 in the Chapter pertaining to “Initial Setup” in the separate Instruction Manual with regard to the initial setup method.
！ WARNING ●When the engine warning lamp in the meter comes on, you must ask the distributor of the model for inspection. If the vehicle is driven at a high speed with the engine warning lamp ON, the engine may be damaged, leading to an unexpected accident. Do not drive the vehicle in this status in any case.
