Installation Guide
The installation guide will guide you through a typical installation. For details on the sensors and devices
mentioned here, see section on Devices and Pin Outs.
Flying Lead Loom Installation on bare engine
The following list outlines the procedure for installing the E11 ECU with a flying lead harness: Unpack your
ECU and identify the following components (some components may vary if you ordered a specific kit):
ECU
Main Wiring Harness
Coolant Temperature Sensor (purchased separately)
Air Temperature Sensor (purchased separately)
MAP Sensor (1, 2 or 3 Bar – purchased separately)
ECU Instruction Manual (which you are reading)
Programming Cable
Programming Disc with Programming Software
Fuse blocks and relays (on wiring harness)
Throttle Position Sensor (optional)
Idle Stepper motor (Optional)
Mounting Devices:
Locate a suitable location for the ECU. Ensure that the loom will reach the necessary parts of the engine
and mount the ECU.
Locate a suitable location for your Fuse block, fuel pump relay, ignition relay, injector relay, ECU relay and
any additional relays used for auxiliary devices (e.g. Thermofan, turbo timers, etc.). Mount all your relays.
Run the loom into the engine bay, but leave the ECU connector disconnected.
Inputs:
Connect the Throttle Position Sensor (TPS).
Connect the Coolant Temperature Sensor.
Connect the Air Temperature Sensor.
Connect the MAP sensor (optional).
Connect O2 sensor (optional).
Connect the crank angle sensor to Trigger (sometimes referred to as a crank trigger). Sometimes these
are driven off the cam, but still give a crank position. Leave the wiring in such a way so that changes to
sensor wiring can be made if required when setting up.
Connect any cam angle sensors if applicable to the Home input. Leave the wiring in such a way so that
changes to sensor wiring can be made if required when setting up.
Outputs:
When running the wiring for outputs, run any power and ground wiring back to the points where they will
be connected, but do not connect power or ground connections yet.
Run the injector wires within the loom to the fuel injectors (each injector shares a common +12V with the
Note: Installation of engine management systems is a complex exercise to be undertaken
only after careful planning and research into the application for which the product is to be
used. Damage to engine components is a distinct possibility if care is not taken during the
installation and setup of the Haltech Engine Management System. If you are unsure about
how to wire any components of your engine, please consult Haltech or an experienced
installer for advice.
