1.3.9 Fuse Block Assembly
The fuse block assembly holds the fuses that protect the various components of the Haltech
system.
The fuse block is supplied from the factory with fuses installed. The fuse ratings are shown in
the diagram and should not be changed except in special circumstances, as these have been
selected for best protection. In some applications where multiple low impedance injectors are
being used, the main 3A ECU fuse may blow. In such applications, please replace this fuse
with a 10A fuse.
The fuse block should be positioned so that it can be easily accessed in case of fuse failure.
Do not mount the fuse block where it could be exposed to water. Mount via the two screws
holes in the block. Ensure that vibration will not cause the screws to vibrate loose.
Connect the Fuse Block assembly to the Main Harness.
1.3.10 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.
1.3.11 Flying Leads

Black (Ground)
