1.2.1 Electronic Control Unit (ECU)
The ECU is not designed to be waterproof. It is desirable that the ECU be given as much
protection from the environment as possible. It is recommended that the ECU be mounted
inside the passenger compartment, either on the firewall, under the dashboard or under the
passenger seat.
The ECU has four mounting holes that allow it to be mounted to most flat surfaces. In
extreme cases of vibration, the ECU should be mounted on rubber anti-vibration pads. When
mounting the ECU remember that the communications connector on the loom should remain
accessible for ease of programming.
Unplug the Delco ECU and plug in the Haltech ECU.
1.2.2 Install and connect the Supplementary Wiring Harness
This small harness connects into the back of the ECU. It provides connection to functions
that are not available on the standard main connector. These are the two trim inputs (fuel and
ignition), two general-purpose Pulse Width Modulation (PWM) outputs (PWM3 &
PWM4) and the communications port. The harness is only about a foot long and can
be removed once tuning is complete, and the communications port, PWM’s and trims are no
longer required.
