*IMPORTANT INFINITY-8H INFORMATION
The primary difference between the 30-7106 Infinity-6 and 30-7108 Infinity-8h is that the 8h lacks Peak
& Hold injector drivers to run low impedance fuel injectors. High impedance (saturated, high-z) fuel
injectors must be used with the Infinity-8h.
The Infinity-6 and Infinity-8h share a common pinout with the exception of four pins where the Infinity-8h
has two each additional fuel injector and ignition coil drivers. Due to the additional fuel injector and
ignition coil drivers, the 8h has two fewer digital inputs and lowside outputs. Use of this harness with an
Infinity-8h will require slight modification and will result in loss of some plug and play function- OEM
Coolant Gauge, Malfunction Indicator Light, and Brake Switch input.

INFINITY CONNECTORS
The AEM Infinity EMS uses the MX123 Sealed Connection System
from Molex. Refer to the 10-7100 for EMS 30-7100 Infinity Quick
Start Guide for details on connector assembly and handling.
AEM strongly recommends that users become familiar with the
proper tools and procedures for working with these high density
connectors before attempting any modifications. The entire Molex
