Relay And Fuse Block Removal/Installation: Installation

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 relocate the terminals one by one so that the installation positions are correct while verifying the wiring diagram.
  • 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.
  • Installing a fuse with the incorrect fuse capacity could damage electronic components and burn wiring harnesses. When relocating the fuses during relay and fuse block replacement, perform the procedures while verifying the wiring diagram so that the installation positions and fuse capacities are correct.
  1. While pressing the stopper using a tape-wrapped flathead screwdriver in the direction of the arrow (1) shown in the figure, pull the wiring harness in the direction of the arrow (2) shown in the figure to detach the fuse terminal from the stopper.
