Used JB4. Was on my 3.3L Kia Stinger for 2 months. Bluetooth, fuel wires, PNP fuel wire adapters, OBD2 connections, as well as spark plug gap tool, feeler gauge, and magnetic socket included. OBD2 clip is broken (see pic), but aso includes a 2nd OBD2 connector (brand new - wire is short and will have to place JB4 on the drivers side to reach). Asking $575 shipped. Located in SoCal and can meet up locally.
