WARNING

  • Never replace a fuse with one that has a higher amperage rating.
  • A fuse with a too-high amperage could damage the electrical part and cause a fire.
  • On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
  • If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
  • Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
