Which Fuse Number Regulates The Illumination Inside?

Interior lighting refers to the various types of lights in and around a car, while exterior lighting covers everything from headlights to taillights. Fuse box diagrams are essential for understanding the location and assignment of fuses and relays in different vehicles. For example, the backlighting is connected to the taillamp fuse and relay, which is a 10A in the IPDM (RH rear of the engine box). The dome lamps go through the Body Computer but are fused.

Fuse boxes can be found on the bottom of the fuse box by releasing two latches located on both sides of the fuse box. For Jeep Wranglers, Honda CR-V Mk3s, and Honda Accords, fuse box diagrams change across years, so it’s important to select the right year.

Keypad illumination, brake shift interlock, start button LED, passive anti-theft system, powertrain control module wake-up, and second row power enable Fuse MINI 20A are also included. The factory fuse table has “ceiling lamps” on fuse 17, which could be for both front and rear lamps.

The body control module sends power to all interior lighting through a purple wire. There are three 10-amp fuses involved with various interior lights, with lift gate lights and front and rear dome lights getting power from the Body Computer. On my 2011 vehicle, it says “Interior Lights” on a 10A fuse at the lower left.

In summary, interior lighting and exterior lighting are crucial components in a car’s operation. Understanding the fuse layout, location, and assignment of fuses and relays is essential for maintaining a functioning vehicle.
