WARNING:
- If a fuse larger than the specified capacity is used, it may cause part damage or a vehicle fire.
Wrap the wiring harness with tape in areas which come into contact with edges and sharp corners of vehicle parts for protection.
When installing parts, do not allow the wiring harness to get caught or damaged.
