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.
