It does not matter which example is used, both will operate correctly. Note that the orange
wires are connected internally within the loom when the relay is closed. As a result it does not
matter which orange wire is used to connect to the fuel pump.
1.3.12 Install and connect Optional Idle Speed Motor
If you are not using the Idle Speed Control, tie the loom connector back neatly in the engine
bay. If the engine has a suitable Idle Speed Motor then you may connect it to the wiring loom,
otherwise you can install a Haltech supplied idle air control motor.
1.3.13 Install and connect any Optional Outputs
If you are planning to use any of the Programmable Optional Outputs, install and connect
them now. Depending on what options you are using, the wiring will be different. For details
on wiring your particular options, refer to CHAPTER 13
Digital Outputs & PWM Outputs,
p88.
1.3.14 Connect the Trigger Sensor
The Trigger is used by the ECU to determine Engine Speed and Position. Some engines have
a second trigger that is used to act as a position reference and is called the “home” signal.
For more information on trigger systems refer 4.2.3 Ignition Set-up Page, p46
When connecting the trigger sensors it is important to identify the type of sensor being used to
measure engine speed and position from the following options: Optical, Hall effect or
Reluctor.
Optical and Hall effect Triggers
Optical and Hall effect triggers behave in a similar way and are treated the same by the ECU
and the term “Hall Effect” should be taken to include Optical triggers.
Hall Effect triggers generally have 3 connections: Power, Ground and signal. As indicated by
the table below, the Power terminal would connect to PIN F, the Ground to PIN A and the
signal to PIN B. If a home or synchronising signal is required the signal terminal would be
connected to PIN E and the Power and Ground to PINF and PIN A respectively.
Reluctor Triggers
Reluctor triggers operate differently and require different wiring and set-up. Reluctor trigger
sensors generally have two connections: Positive and Negative (often labelled “+” and “-”).
As indicated by the table below, the positive connection would connect to PIN B, the negative
to PINC. If a home or synchronising signal is required the positive terminal of the home
sensor connects to PIN E and the negative to PIN D.
