*IMPORTANT INFINITY 508 INFORMATION
The primary difference between the
30-7106 Infinity 506
and
30-7108 Infinity 508
is that the 508 lacks
Peak & Hold injector drivers to run low impedance fuel injectors. High impedance (saturated, high-z)
fuel injectors must be used with the Infinity 508.
The Infinity 506 and Infinity 508 share a common pinout with the exception of four pins where the
Infinity 508 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 could result in loss of some plug and play
function.

System from Molex. 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 MX123 User Manual can
