OVERVIEW

The 30-3500 AEM Infinity Adapter Kit is designed for the 1993–1998 Toyota Supra MKIV Twin Turbo
(manual transmission). 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:

30-7100 INFINITY-8
30-7101 INFINITY-10

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. Toyota Supra MKIV Twin Turbo base sessions are located in C:

INFINITY CONNECTORS

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 1993–1998 Toyota Supra MKIV Twin Turbo kit is an adapter harness. This is used to

Many Toyota, Mitsubishi, and other vehicles use an Idle Air Control Valve with a Unipolar Stepper Motor
(6-pin connector) and MUST be modified. See instructions below. A Bipolar Stepper Motor (e.g., GM)
will have a 4-pin connector and DOES NOT need to be modified.

*This info does not apply to vehicles that utilize IACV solenoids.

The 2 center pins (Black-Red wires) supply 12V power to the stepper motor in the factory setup,
however these pins MUST BE DISCONNECTED before powering the AEM Infinity ECU.
