AEM 30-3805 Infinity Universal Core Wiring Harness
AEM’s Universal Core Harnesses allow you to easily assemble a crate motor engine harness for using the Infinity ECU on your GM small block or big block engine. The Core Harnesses have High-Performance DTM-Style connectors that allow you to plug in sub harnesses for injectors, ignition adapter, cam/crank signal, and idle control.
COMPREHENSIVE CORE HARNESS DESIGN
AEM’s Universal Core V8 Wiring engine harness (PN 30-3805) is terminated with Infinity Series 7 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 HARNESS
An injector adapter harness is available for GM engine injector locations and cylinder numbering (PN 30-3805-10 GM). It connects to the Universal V8 Core Harness via a High-Performance DTM-Style connector and includes the popular/common Bosch EV6-style connectors for the fuel injectors. This harness includes labels for ease of installation and is 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 15" Leads for Rear Mounted Distributor (PN 30-3805-14)
- 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.
GM DRIVE-BY-WIRE HARNESSES
AEM offers a GM Drive-By-Wire Pedal sub-harness (PN 30-3809-00) that connects to the Infinity Series 5 Universal V8 Core Harness via a High-Performance DTM-Style connector and is terminated at the opposite end for the GM PN 10379038 pedal assembly. AEM also offers a GM Drive-By-Wire Throttle Body sub-harness (PN 30-3809-01) that connects to the Infinity Series 5 Universal V8 Core Harness via a High-Performance DTM-Style connector and is terminated at the opposite end for the GM PN 12570790 & 12580760 throttle body. Making the connection of your GM DBW assemblies a simple plug & play application.
