AEM Infinity Series 508 Plug and Play Engine Harness for GM/Chevy LS 58X

By far the most common swap around the world today is the GM LS series of engines. Whether you have a hot rod or a race car you want to make sure that engine is running as good as it can and thanks to the AEM Infinity and AEM's Plug & Play Engine Wiring Harness for GM LS race engines with a 58X timing pattern (30-3801) having a motorsports grade harness and engine management system is a plug and play affair. The AEM PnP harness is a comprehensive, high-quality wiring harness that allows you to easily and affordably integrate the Infinity-508 Programmable ECU onto your 58X LS engine. The harness plugs into the factory coil sub harnesses and utilizes the factory sensors. It includes a Wideband O2 connector for use with a Bosch 4.2 LSU UEGO air/fuel ratio sensor (30-2001) and for an easy install we recommended that you purchase a Wideband Extension Cable (30-3600).

A Complete Standalone EFI System for GM/Chevy 58x LS Engines

The 30-3801 58X LS Infinity wiring harness harness utilizes Automotive-grade, color-coded wiring and the timing inputs (cam and crank sensors) are shielded for minimizing EMI. Water and shock-proof factory connectors for the sensors are used throughout the harness, as well as DTM-style connectors for auxiliary components. The IP67-rated ECU connector is designed to mate with AEM’s Infinity-508 ECU. Connections for a wideband O2 sensor, Drive-by-Wire and pedal, Knock, and AEMnet (AEM’s CANbus) are integrated into the harness.

An integrated fuse and relay panel includes five relays and seven fuses that provides robust power distribution, engine circuit protection, and easier integration of additional features. Relays with flying leads are included for the fuel pump and fans. The panel’s housing is weather resistant and panel lid is weatherproof for added protection.
