AEM Infinity Series 5 Universal Core Wiring Harness

AEM’s Universal Core & Accessory Wiring Harnesses simplify the installation of an Infinity ECU on any 4-, 6- or 8-cylinder application with an Infinity-supported crank/cam timing configuration.

The Universal Core Harness combines injector sub harnesses with ignition timing sub harnesses for every type of MAG and Hall Effect timing configuration, allowing racers to get an Infinity-tuned racecar wired quickly and accurately. Idle motor sub harnesses for Ford and GM are available for easy integration onto Ford & Chevy Small Blocks and Big Blocks. An ignition adapter sub harness for AEM’s Single Channel Coil Driver is available for triggering an inductive coil directly or a single-channel capacitive discharge ignition (CDI). Ignition sub harnesses for the AEM EPM and other popular ignition systems are also available.

COMPREHENSIVE CORE HARNESS DESIGN

AEM’s Universal Core V8 Wiring engine harness (PN 30-3809) is terminated with Infinity Series 5 ECU connectors, power/ground leads and an OEM power distribution block with 5 relays and 7 fuses. Special care was taken to build redundancy into the power distribution system to increase overall reliability.

High-Performance DTM-Style connectors terminate the leads for dual UEGO wideband air/fuel ratio sensors, wheel speed sensors, AEMnet (AEM’s CAN bus), dual 8-pin auxiliary ports, cam & crank, idle, injectors and coils sub harnesses. High-Performance DTM-Style connectors and pins are included for the auxiliary ports. Flying leads are included for permanent and switched power, manifold pressure (MAP), oil pressure, fuel pressure, air temperature, coolant temperature, and throttle position.

The wiring is covered in an automotive-grade loom for enhanced longevity and the power/ground leads are heavy-duty serrated versions to ensure the best connection. A firewall grommet is included for a clean pass-through. All wires and connectors are labeled for ease of installation.

INJECTOR SUB HARNESSES

Injector adapter harnesses are available for Ford and GM engine injector locations and cylinder numbering. They connect to the Universal V8 Core Harness via a High-Performance DTM-Style connector and include the popular/common Bosch EV1-style connectors for the fuel injectors. These harnesses include labels for ease of installation and are covered in an automotive-grade loom for longevity.

CAM/CRANK TIMING SIGNAL HARNESSES

AEM has made the task of configuring and wiring cam/crank signals as easy as the snap of a High Performance DTM-Style connection. Timing sub harnesses are available for:

• MAG Cam/Hall Crank (PN 30-3805-05)
• AEM EPM 35″ Leads for Front Mounted Distributor (PN 30-3805-19)

High quality shielded wiring is used to virtually eliminate EMI and the flying leads for crank position, cam position, power, and grounds are labeled for ease of installation.
