The Chevy 58x LS Plug & Play engine harness (PN 30-3801) pairs with the Infinity 508 (PN 30-7108). AEM’s Plug & Play engine harness for GM 58x LS engines includes a Wideband O2 connector for use with a Bosch 4.2 LSU UEGO air/fuel ratio sensor (PN 30-2001) and a Wideband Extension Cable (PN 30-3600 x 1) is highly recommended to ensure enough length to properly mount the wideband sensor. This harness uses the factory sensors and coil sub harnesses to make integration onto the engine simple and straightforward. IP67-rated ECU connectors are designed to pair with AEM's Infinity 508 ECU, and the 58x harness includes integrated connections for a wideband O2 sensor, Knock, Drive-By-Wire and pedal, injectors and more.

A Complete Standalone EFI System for Chevy 58x LS Engines

The Infinity 508 ECU combines with a GM 58x LS Plug & Play engine harness to retain full control of the engine’s functions. It is ideal for crate motor solutions that are using aftermarket dashboards as they can be configured using the on-board CANbus (will not communicate with the factory dashboard on GM LS equipped vehicles).

The Infinity ECU is able to control the variable valve camshaft and drive-by-wire on equipped LS engines, providing tuners with the ability to take full advantage of the engine’s low-end power potential, and eliminate the need to convert to cable throttle. Users can create two drive-by-wire profiles for rain maps, pit lane limits and more.

AEM’s LS PNP Engine Harness also eliminates the restrictive factory mass airflow sensor (MAF) and airbox, making it an ideal harness solution for forced induction applications. Other key racing features include multiple boost control strategies, programmable nitrous control, on-the-fly map switching, programmable two-wheel speed traction control, launch control, flex fuel and multi-fuel capability. It utilizes airflow (VE) based tuning, has up to 64GB data logging capacity and can transfer data at up to 480Mb/second. Its enclosure is sealed and suitable for engine bay mounting.
