Kia/Hyundai/Genesis JB4 PNP Fuel Wire Adapter This optional plug and play quick install adapter allows you to install a posi-tap for fuel control tuning without piercing the factory o2 sensor wiring providing a completely reversible connection. For 3.3L models the signal wire is red for easy identification. For 2L models the signal wire is the black wire on position #2. To find position #2 just look at the small numbers on the adapter itself. For 1.6L models it can be either depending on the model year and ECU software. *** NOTE FITS JB4 Kia/Hyundai V1 applications only -- V2-V4 do not use an o2 sensor connection ***
