Red
(Battery Supply +12V) Locate a source of continuous +12 volts and connect the red
wire. Connecting direct to the positive battery terminal is suggested.
Grey
(Ignition Switched +12V) The grey wire is used to control the operation of the ECU
power relay. It needs to be connected so that it sees 12V only when the ignition switch
is on and during cranking. This wire does not draw a large amount of current (< 0.5A).
Do not connect to the accessory outputs of the ignition switch since +12V is not
available during cranking in many cases.
Green
(Aux In) The green wire is used as the Aux In channel. The Aux In channel is used by
a number of functions and is further described in 4.2.4 The In/Out Set-up Page, p49)
The following diagram is an example of how to wire the Aux In circuit:

Orange
The two orange wires are used to operate the fuel pump. When the ECU wants to
operate the fuel pump it will close the fuel pump relay connecting the two orange
wires together. The diagrams show two examples of wiring the fuel pump. Do not add
extra relays to the fuel pump circuit.
Example 1: Connecting to the positive side of the fuel pump.
Example 2: Connecting to the negative side of the fuel pump.
