DISCLAIMER

Haltech will not be held responsible for any damage caused by the incorrect installation or tuning of this product. It is the installers responsibility to ensure the wiring connections and pinouts match that of the vehicle the unit is being installed into.

Haltech has taken all care to make sure the connections match the specified vehicles listed, but variations in wiring and connections on vehicles can occur and therefore this should be checked BEFORE the unit is installed.

Haltech highly recommends installation and tuning of this product is to be carried out by a professional, with an understanding on installing and tuning engine management systems. Misuse of this product can destroy your engine.

WARNING

This ECU is designed and sold for Racing use only. Using this product for street / road use may be prohibited by law. Please check with your local vehicle authority before using this product.

GENERAL INSTALLATION WARNING

Avoid open sparks, flames or operation of electrical devices near flammable substances. Always disconnect the battery cables when doing electrical work on your vehicle.

Do not charge the battery with a 24 Volt truck charger or reverse the polarity of the battery or any charging unit. Do not charge the battery with the engine running as this could expose the ECU to an unregulated power supply that could destroy the ECU and other electrical equipment.

All fuel system components and wiring should be mounted away from heat sources, shielded if necessary and well ventilated. Disconnect the Haltech ECU from the electrical system whenever doing any arc welding on the vehicle by unplugging the wiring harness connector from the ECU.

After completing the installation, make sure that there are no fuel leaks, and no wiring left un-insulated in case a spark or short-circuit occurs and causes a fire. Also make sure that you follow all proper workshop safety procedures. If you're working underneath a jacked-up car, always use safety stands!

Quick Start Guide

Congratulations on purchasing a Haltech I/O Expander 12 This Plug and Play product allows the user the ability to increase the functionality of their Haltech ECU by using the Haltech CAN system which is fitted to all Platinum Series ECU's.

The Haltech I/O Expander 12 instantly makes available 12 additional user configurable inputs and outputs. Simply plug in the CAN cable and start using your extra I/O.

This quick start guide will walk you through installation of the Haltech I/O Expander 12 into a vehicle. This guide is accompanied by the full service manual located on the software CD provided with the ECU that you or your tuner will need to refer to before completing your installation and configuration. The Manual can also be downloaded from the Haltech website www.haltech.com.

Installation

Installing the Haltech I/O Expander 12 is quick and simple there are 2 possible methods for connection to your Haltech ECU, they are outlined below:

Method 1: Direct Connection to Haltech Platinum Series ECU

• Connect the Haltech I/O Expander 12 directly to a Haltech Platinum series ECU via

the CAN direct connection cable included with the kit

Figure 1 – Direct connection to Haltech ECU

Method 2 : Connection Via Haltech CAN Hub ( HT059990)

• Connect the Haltech I/O Expander 12 directly to the CAN Hub attached to a Haltech

Platinum Series ECU ( a Haltech CAN Hub Connection Cable may need to be purchased depending on your setup. Please refer to the Haltech CAN Hub quick start guide for details on connecting multiple devices to your Platinum Series ECU.)

Wiring Harness (optional)

The Haltech I/O Expander 12 can be supplied with a 24 pin wiring harness, Connections are outlined in detail below:

WARNING!

Please make sure you configure your I/O Expander 12 with your ECU using

ECU Manager Software before you plug in the wiring harness, as outputs may

turn on undesirably when power is applied if not configured.

Main Inputs

There are four main inputs to the Haltech I/O Expander 12

+12V DC Switched (Pink)

Connect this wire to a +12V DC Switched ignition source

+12V DC Battery (Red)

Connect this wire to a constant +12V DC battery supply

Signal Ground (Black / White)

Connect this wire to the signal ground on the ECU

Ground (Black)

Connect this wire to a chassis ground point on the vehicle

Figure 1- Main inputs

Digital Pulsed Inputs ( DPI )

The Haltech I/O Expander 12 features 4 Digital Pulsed Inputs. Each input has been grouped with a +12V DC Source and a signal ground within the harness, this allows the user to fit an external pull-up to 12V or pull- down to ground resistor if required and or to supply power to a 12V rated sensor. Digital Pulsed Inputs are capable of accepting pulsed input information such as for a road speed sensor. These inputs measure the time periods between the pulses and can process this information to provide quantities such as road speed.

Analogue Voltage Inputs ( AVI )

The Haltech I/O Expander 12 features 4 Analogue Voltage Inputs. Each input has been grouped with a +5V DC Source and a signal ground within the harness, this allows the user to fit an external pull-up to 5V or pull-down to ground resistor if required and or to supply power to a 5V rated sensor.

Analog Voltage Inputs accept variable voltage inputs from 0V to 5V. AVI inputs can also accept switch inputs that change between two different voltage levels. The On Voltage and Off Voltage define the thresholds between the On and Off states. The input voltage can be viewed as a channel in the software to determine the thresholds for a switched input.

Digital Pulsed Outputs ( DPO )

The Haltech I/O Expander 12 features 4 Digital Pulsed Outputs. Each output has been grouped with a +12V DC Source within the harness, this allows the user to fit an external relay to control high current devices. Digital Pulsed outputs are capable of outputting pulsed waveforms with varying duty and frequency. DPO's can be used to control various devices such as thermo fans, shift lights, bypass air control valves, boost control solenoids etc. When a Digital Pulsed output is activated by the ECU the output will switch to ground. Solenoid valves and shift lights etc can be run directly from the output. However high current devices such as thermo fans and additional fuel pumps must be activated through a relay. This way the DPO is only switching a relay and not a high current draw device.

Digital Pulsed Outputs are limited to 1A Max current draw.
