BMW Electrical Sensors, Switches, & Relays for BMW 4 Series F32 (2014+)

Clear BMW chassis

Please ensure your correct model is selected

Electrical gremlins can be very frustrating. Luckily your BMW's electrical system is better than most, even if it's 25 years old. Here you will find electrical relays, sensors, switches, and modules for the engine, camshaft, and crankshaft. Our parts are OEM, Genuine BMW, or approved aftermarket brands that we have an excellent track record with. There is no middle ground with electrical parts - it either works perfectly or not. And there's nothing more frustrating than a new part that fails right out of the box. So it's important to choose quality replacement parts over a cheap but faulty piece.

The **Precision Raceworks S58/B58 Plug-and-Play Install Harness for the Motiv ReFlex+** is certified by Motiv Motorsports and is an essential upgrade for anyone integrating a ReFlex+ into their S58 or B58 vehicle. This Harness replaces only the signal and power sub harness portion of the Motiv Reflex. Standard universal Motiv ReFlex Plus harness required for use of this Plug and Play Harness - ES#4810312 / ES#4810314 This innovative harness eliminates the need for cutting, crimping, or splicing into your factory wiring, providing a straightforward, fully reversible installation. Simply plug it in, and you're ready to go! ### Why Choose the Precision Raceworks Harness?
