1Introduction

Several universal wiring harness options are available for Infinity products. They range
in complexity from simple plug and pin kits to complete engine harness assemblies that
include power distribution centers. Custom wiring harness projects should only be
undertaken by experienced harness builders. If in doubt, please contact AEM for
recommendations.

can be used as a reference for any custom harness build based on the Infinity ECU.

Please read the entire User Manual prior to beginning any installation.

2Optional Extension Harnesses for Modular Harness System

Optional extension harnesses compatible with the 3805 V8 harness system are
available.

30-3805-00 GM Injector Adapter Harness

Adapter harness that mates EV1 style injectors in standard GM cylinder order (odd
cylinders on one bank, even cylinders on other) to 30-3805 Core Harness.

30-3805-01 Ford Injector Adapter Harness

Adapter harness that mates EV1 style injectors in standard Ford cylinder order
(cylinders 1-4 on one bank, cylinders 5-8 on other) to 30-3805 Core Harness.

30-3805-02 Single Channel Ignition Adapter Harness

Adapter harness that mates AEM Single Channel Coil Driver (30-2841) to 30-3805
Core Harness. Coil driver takes 5v falling edge ignition trigger signal from Infinity and
outputs a 12v rising edge signal. 12v rising edge signal can either be used to trigger an
inductive coil directly or trigger a single channel CDI box (MSD 6A, etc).

30-3805-03 VR Crank & VR Cam Adapter Harness

Adapter harness that mates variable reluctance (VR) crank and cam sensors to 30­3805 Core Harness. Legs to each sensor are 48” long.

30-3805-04 VR Crank & Hall Cam Adapter Harness

Adapter harness that mates variable reluctance (VR) crank sensor and Hall Effect cam
sensor to 30-3805 Core Harness. Legs to each sensor are 48” long.

30-3805-05 Hall Crank & VR Cam Adapter Harness

Adapter harness that mates Hall Effect crank sensor and variable reluctance (VR) cam
sensor to 30-3805 Core Harness. Legs to each sensor are 48” long.

30-3805-06 Hall Crank & Hall Cam Adapter Harness

Adapter harness that mates Hall Effect crank and cam sensors to 30-3805 Core
Harness. Legs to each sensor are 48” long.

30-3805-07 GM Stepper Idle Control Adapter Harness

Adapter harness that mates GM stepper idle control valve to 30-3805 Core Harness.
IAC connector is flat and meant for use with later model style control valves.

30-3805-08 Universal PWM Idle Control Adapter Harness

Flying lead to mate universal PWM idle control valve to 30-3805 Core Harness.
Connector to connect to control valve must be provided by end user.
