Show original supplier description
The Visconti Tuning ReFlex+ Plug and Play Install Harness is specifically engineered for BMW S58 and B58 engine platforms, providing a seamless integration solution for the MOTIV ReFlex+ controller. This harness completely bypasses the need for cutting, crimping, or splicing factory wiring, ensuring a clean and reversible installation. It enables the MOTIV main harness to connect directly to the vehicle's existing electrical system. This kit is an ideal solution for both new installations and for rectifying issues caused by previous improper wiring, such as incorrect crimping or T-tapping. By retaining the factory main harness, it avoids the labor-intensive task of replacing injector wiring, especially on vehicles equipped with a port plate. The ReFlex+ Plug and Play Install Harness offers broad compatibility with popular tuning platforms, including EcuTek, MHD+, BM3, and MG Flasher, provided they are used in conjunction with the Motiv Motorsport ReFlex+ controller. This harness is constructed with automotive-grade wiring for durability and is proudly made in the USA in an IOS 9001 certified facility. Each harness undergoes pre-shipping testing to guarantee reliability. Included in the kit are the Visconti Engine Harness (CAM/CRANK), Visconti Flex Fuel Sub Harness (CAN bus, Power, Ground, Ethanol), and the Visconti MOTIV Main Integration Harness. An optional Visconti Charge Pipe Harness is included for BM3 & MG Flasher tuning platforms. It is important to note that this kit does not include the MOTIV ReFlex unit itself, nor does it include fuel lines, adapters, or a flex fuel sensor.
