Description

This HKS F-CON Harness NP5-21 is exclusively for Power Writer shops and is compatible with F-CON V Pro Ver.3.4 or F-CON V Pro Ver.4.0. Installation may trigger the Check Engine Light (CEL) for Air/Fuel ratio errors, but driving is still possible. Do not remove the airflow sensor during installation. Converting airflow sensor voltage to a dummy signal may increase shift shock. If valve timing is controlled by F-CON V Pro Ver.4, CELs related to valve timing and/or air/fuel ratio may appear; the F-CON V Pro CF adapter can resolve these symptoms.
