Overview

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.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
