AEM Infinity-8h GM LS 58X Plug & Play Engine Harness

With the worldwide popularity of the GM LS family of engines, AEM have released their new Plug & Play wiring harness to suit the LS series V8 engines utilising a 58x trigger pattern. This harness allows easy integration with the Infinity-8h standalone ECU with these engines by plugging into the factory coil sub harness and existing factory sensors. With the harness selling for $599.95 and the infinity-8h for $1290.50, this makes for a full standalone EFI system/harness combination for under $2000.00 USD. This price still includes all of the standard Infinity features such as traction control, drive by wire throttle control, data logging and engine protection strategies.
The harness utilises automotive grade wiring with a quality braided mesh overlay and the trigger inputs are shielded for optimum signal reliability. Water and shock-proof factory connectors for the sensors are used throughout the harness, as well as DTM-style connectors for auxiliary components. Additional connections for a wideband O2 sensor, drive by wire throttle pedal and knock 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.
