Wire Harness LS 58x/4x Front Cam Sensor

The MSD IGNITION Wire Harness LS 58x/4x Front Cam Sensor (MSD part number 2278) is a precision ignition wiring harness designed specifically for LS-platform engine conversions and high-performance engine management systems. This harness is essential for establishing the signal path between the front-mounted camshaft sensor and the MSD ignition control module, ensuring accurate fuel and ignition timing for engines equipped with 58x or 4x crankshaft reluctor wheels.

Manufactured to exact specifications, this harness addresses common issues such as signal noise and timing errors that can occur in custom engine installations. It is built to maintain sensor signal integrity, which is crucial for stable idle quality, smooth throttle response, and reliable cold-start operation on modern LS architectures. Proper integration of the front cam sensor signal allows the ignition control system to accurately synchronize fuel injection and spark timing across all operating conditions.

Ideal for builders and technicians working on LS engines in non-original platforms or upgrading existing LS installations, this harness supports both classic car restorations and performance crate engine builds. The 58x reluctor wheel configuration is standard on modern LS variants, providing high-resolution crankshaft positioning for advanced fuel and spark control. This product is a reliable choice for anyone looking to enhance their engine management system.
