Check the front-mounted electrical panel behind the dashboard and locate the ceramic strip connectors assigned to lighting and ignition circuits; these components are arranged in a horizontal row and numbered from left to right.
Each slot uses European-style ceramic elements with visible metal bridges, typically rated between 8A and 16A. Matching the amperage stamped on the metal caps prevents overheating and protects wiring linked to headlights, wipers, and cabin systems.
Pay attention to wire colors connected to each terminal; for example, white wires often indicate headlight circuits, while black or red wires relate to ignition-switched power. This color coding simplifies tracing electrical paths without removing large sections of wiring.
Access requires removing the lower dash cover and carefully pulling the panel forward. Ensure tight contact between connectors and metal clips, since loose fittings lead to intermittent power loss, flickering lights, or non-working accessories.

Locate the front dash-mounted electrical strip and align each ceramic holder from left to right, where positions 1–4 typically serve lighting circuits and the remaining slots handle ignition-switched accessories and auxiliary systems.
The panel uses open-style holders with visible metal bridges, allowing quick inspection; each connector pair links to a specific wire color set, such as white for headlights, yellow for low beam routing, and black for ignition-fed lines, which helps trace circuits without disconnecting harnesses or removing additional components.
Exact Fuse Positions for Headlights Ignition and Interior Circuits
Identify the first four ceramic holders on the left side of the panel as headlight circuits, where two positions control low beam and two handle high beam, each connected through white and yellow wiring for clear separation of lighting modes.
The middle section typically supplies ignition-fed systems, with black wires leading from the switch to components like the coil and dashboard indicators, while the right-side positions manage cabin lighting and auxiliary features such as wipers or heater fan; checking wire color and terminal pairing confirms each circuit without guesswork and helps avoid placing incorrect amperage inserts that may cause wiring damage.
