WA RNING

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!

Harness Overview

The Haltech GM LS2 / LS3 Terminated Engine Harness is a plug and play solution
for wiring a General Motors LS2 or LS3 Engine.

Installation is simple and easy as the harness is designed for the engine, all lengths
are correct and all wires are clearly labeled.

Notes on installation:

• Make sure your Engine is grounded directly to the chassis of the vehicle.
A heavy gauge ground / earthing strap should be used to ground your engine to the
chassis of the vehicle. The Haltech Terminated Engine harness does not ground
your engine.

WARNING!

Damage can occur to your harness and / or ECU if you do not ground

your engine properly. Please ensure heavy gauge cable is used.

• Keep all wires away from the Exhaust manifold.

• The harness is designed to plug directly into the OEM ignition loom and therefore

no ignition loom is supplied

• A cable operated throttle body is required to be retrofitted to the engine

• Basemaps are available on the website www.haltech.com.au

Termination Descriptions

Analogue Voltage Inputs (AVI-5, Fuel-P, Oil-P)

The Analogue Voltage Inputs can accept variable voltage inputs from 0V to 5V.
These inputs can also accept switch inputs that change between two different voltage
levels. The on voltage and off voltage define what the thresholds are between the on
and off states. The voltage can be viewed as a channel in the ECU Manager software
to determine thresholds for a switched input.

Fuel Pressure Sensor (Fuel-P)

The Fuel-P labeled connector connects directly to the fuel pressure sensor on the
engine. This will enable the user to know the current fuel pressure of the vehicle.

Oil Pressure Sensor (Oil-P)

The Oil-P labeled connector connects directly to the oil pressure sensor on the engine.
This will enable the user to know the current oil pressure of the vehicle.

Analogue Voltage Input 5 (AVI-5)

The AVI-5 labeled connector is a spare Analogue Voltage Input (AVI-5).
The 4 pin connector has the following terminations,
Please isolate all unused terminations.

Pin # 1 – Blk/Wht : Sensor Ground
Pin # 2 – Org : +5V Sensor Power
Pin # 3 – Org/Grn : Sensor Signal
Pin # 4 – Unpopulated

This input can be programmed within the ECU Manager Software to read inputs
such as:

• 02 Sensors

• Pressure Sensors

• Temperature Sensors

• Various Switches

• Trim Module

ECU Manager Software.
