Powering up the ECU
The main power wire must be wired via the shortest route possible to the battery
positive terminal. The main power to the ECU must be connected to the battery and
NOT the ignition switch, the ignition switch will not be able to handle the current
required to operate the ECU (there is an additional pink wire within the Platinum Sport
loom that connects to the ignition switch to switch the ECU on).
Three Positive Cables need to be connected to the battery from the loom
( 1 x 2mm Red/Green , 1 x 2mm Red, 1 x 0.5mm Red/White )
To avoid damage to ignition components, never connect the ignition modules to the
ECU until the ECU is configured. The same applies to the fuel system, never connect
fuel injectors until the ECU is configured, otherwise the engine may flood with fuel.
Grounding
One of the most common wiring problems experienced is poor grounding. There
should be no paint, anodising or other surface layer protection between the ground
wire and engine block or chassis. Temporary wiring will almost certainly cause a
problem, use a proper ground eyelet terminal and do not use loctite or similar
locking agents as they may become insulators preventing good earth connection.
Chassis Ground (Black) should be connected to the chassis of the vehicle, and
Signal Ground (Black / White) should be connected directly to the Battery negative terminal.
Please make sure your Engine block has a ground strap to the chassis.

The
Haltech CAN Network
The Haltech CAN network allows for simple and effective expansion in ECU capability
and functionality without having to go to the trouble of wiring in a whole new computer.
Expansion is made possible by the addition of multiple expansion devices that
communicate to the main ECU via a Control Area Network (CAN).
Installation time and costs are kept to a minimum as all expansion devices are
powered up from the main ECU via the pre-terminated connection cable that comes
with each expansion device.
Simply connect the device directly to the 8 pin CAN connector on the rear of the ECU
or connect using an optional Haltech CAN Hub (order as part # HT059991) if multiple
expansion devices are required).
Each expansion device is pre-programmed with a unique ID code which allows it to
be recognised on the network and work correctly first time every time.
For current available expansion devices please go to our website at
