  2. Relocate all relay and fuse terminals to the new relay and fuse block.
    CAUTION:
    • If terminals are installed incorrectly, it could damage electrical accessories and burn wiring harnesses. When relocating terminals after replacing the relay and fuse block, line up the relay and fuse blocks of old and news parts and always verify each of the wiring harnesses in the wiring diagram so that the installation positions are correct.
    • A terminal disconnection could cause electronic components and the system to not operate normally due to poor contact. After terminal relocation, lightly pull the wiring harnesses to verify that they cannot be pulled out.
