The fuse block assembly holds the fuses that protect the various components of the Engine Management System. The fuse block is supplied from the factory with fuses installed. The fuse ratings and connections are shown in the wiring diagram above, and also on the inside of the fuse block lid. The fuse ratings have been selected to protect the Haltech ECU and the electrical systems that supply it. Fuse ratings should only be changed if the expected normal load current exceeds the factory specification. Altering the fuse ratings could cause severe damage to the system.
The fuse block should be positioned so that it can be accessed easily in case of fuse failure. Do not mount the fuse block where it could be exposed to water. mount the fuse block using the two screws holes in the block ensuring that vibration will not cause the screws to vibrate loose.
