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.
It does not matter which example is used, as 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.
1.3.11 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.
1.3.12 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 12 Digital Outputs & PWM Outputs,
