OVERVIEW

The 30-3502 AEM Infinity Adapter Kit was designed for the 2001–2005 Honda K Series. This is a true
standalone system that eliminates the use of the factory ECU. The use of this adapter makes the kit
“plug and play” so no cutting or splicing wires is necessary. The base configuration files available for the
Infinity EMS are starting points only and will need to be modified for every specific application.

*The AEM Infinity EMS will not support the factory A/C Switch and Coolant Gauge that are driven by
Honda's Multiplex System.

The available AEM Infinity EMS part numbers for this adapter kit are:

30-7106 INFINITY-6
30-7108 INFINITY-8h

GETTING STARTED

Refer to the 10-7100 for EMS 30-7100 Infinity Quick Start Guide for additional information on getting
the engine started with the Infinity EMS. The base session is located in C:\Documents\AEM\Infinity
Tuner\Sessions\Base Sessions

DOWNLOADABLE FILES

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 could result in loss of some plug and play function.

INFINITY CONNECTORS

The AEM Infinity EMS uses the MX123 Sealed Connection
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 be
downloaded direct from Molex at:

INFINITY ADAPTER HARNESS

Included with the 2001–2005 Honda K Series kit is an adapter harness. This is used to make the
connection between the AEM Infinity EMS and the Honda wiring harness plug and play. This is depicted
below with the 80-pin connector and the Honda header. There are also a few other integrated connectors
within this harness described below.

The gray Deutsch 6P DTM “LAMBDA” connector is for connecting a UEGO wideband Bosch LSU4.2
sensor (AEM 30-2001). The UEGO extension harness (AEM 30-3600) mates the adapter harness to the
sensor.

The gray Deutsch 4P DTM connector is used for “AEMNET”. AEMNet is an open architecture based on
CAN 2.0 which provides the ability for multiple enabled devices, such as dashboards, data loggers, etc.,
to easily communicate with one another through two twisted cables (CAN+/CAN-).

The black Delphi 2-pin “FLASH” connector is used for secondary hardware flashing. The included shunt
connector jumps the 2 wires together. Once initially flashed, the EMS is normally upgraded in the
software, not using this connector.

The red flying lead labeled “Battery+” is to be connected to a permanent +12V source. This source
should be independent of the ignition switch. The OEM Honda ECU does not have a permanent +12V
power pin, so this must be sourced separate from the OEM connector and should be protected with a 5A
fuse.
