OVERVIEW
The 30-3509 AEM Infinity Adapter Kit was designed for the 1999–2001 Honda B-H-D Series OBD2b. 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 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
Files can be downloaded from www.aeminfinity.com. An experienced tuner must be available to configure
and manipulate the data before driving can commence. The Quick Start Guide and Full Manual describe
the steps for logging in and registering at www.aeminfinity.com. These documents are available for

Infinity-8h.
*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 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

INFINITY ADAPTER HARNESS
Included with the 1999–2001 Honda B-H-D Series OBD2b 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 6P DTM “COIL” connector is for ignition output. Using with the included jumper
connector runs distributor application. Coil-on-Plug conversion requires some custom wiring and setup
with Infinity tuner software.
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 6P DTM “COIL” connector is for ignition output. This connector has been configured to
allow the triggering of four individual coils by interfacing with this connector. AEM offers the 30-3501-00
Honda Coil Adapter for use with the OEM Honda distributor’s internal coil. This adapter is required if
the OEM distributor and ignition coil are to be used.
