AEM Performance Electronics has just released their Infinity engine harness for LS crate engines, or modified LS racing engines. Now, a higher level of engine control is available for an affordable price. The Plug & Play design is a great solution for those using the Infinity-508 programmable ECU.
This harness plugs into the factory sub harnesses and uses the factory sensors. Combined with the Infinity-508 ECU, the LS Plug & Play harness allows users to maintain full control of the engine’s functions. This high-quality harness is easy to install and built to last. Learn more about it in the official release below.
Official Release:
AEM Releases GM LS 24x Plug & Play Engine Wiring Harness for Infinity ECU!
AEM has released its Plug & Play Engine Wiring Harness for GM LS race engines with a 24x timing pattern (PN 30-3821, retail price $676.07). This comprehensive, high-quality wiring harness allows racers to easily and affordably integrate the Infinity-508 Programmable ECU onto their 24x LS race engine by plugging into the factory coil sub harnesses and using factory sensors (OEM ignition coil sub harnesses are not included). It mates to the Infinity-508 ECU (PN 30-7108), which carries a retail price of $1,399.95, making a full standalone EFI system/harness combo with integrated traction control, data logging with video overlay, engine protection and more available for under $2,100.00! The 24x harness also includes a connection for drive-by-wire (DBW) if users want to add this feature.
The harness utilizes Automotive-grade, color-coded wiring and the timing inputs (cam and crank sensors) that are shielded for optimum performance. 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 CAN bus) 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.

The Infinity ECU makes state-of-the-art ECU technology affordable for both professional teams and amateur racers. It delivers complete control of GM 24x LS engines including traction control and Drive-by-Wire, advanced features including map switching, six spare inputs/seven outputs, flex fuel, boost control, nitrous control and data logging, and advanced tuning like individual cylinder knock control, oil/fuel/lean/coolant/overboost engine protection, 10×20 individual cylinder fuel trim tables, 8×8 injector load phasing tables and 10x RPM individual cylinder ignition trims tables.
Built around a latest-generation 32 bit floating point 200MHz automotive processor and Real Time Operating System (RTOS), the Infinity is capable of processing 400 MIPS (millions of instructions per second). To our knowledge, the Infinity ECU currently has the fastest processing speed of any aftermarket Motorsports ECU available. This processing speed combined with a RTOS provides more accurate ignition timing for increased power, more responsiveness to truly custom tailor the driving experience to the driver, allows the Infinity to perform more computational features without a sacrifice in processing performance, and enables tuning of features and sub strategies without affecting other features and sub strategies. It allows you to do more, faster, in a more stable programming environment.
Note: This GM LS Plug & Play Engine Harness is for 24x Timing Pattern LS Engines using Infinity-508 ECU. It is also intended for vehicles sanctioned for racing.
