Page 3: Precaution On Installation
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. - Page 4 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.

Page 8: Initial Setup
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. - Page 9 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.
