Check the cabin panel under the dashboard on the driver side and match each slot with the printed legend before removing any component. Use only the specified amperage such as 10A, 15A, or 20A to prevent wiring damage or module failure.
The engine compartment unit near the battery contains high-current links and control relays for systems like radiator fan, ignition, and fuel delivery. The cover map shows exact positions, helping identify each protected circuit quickly.
If an electrical system stops working, test related slots using a multimeter or test light. A broken internal strip or lack of continuity indicates a failed component, while a working one will pass current without interruption.
Interior circuits typically include lighting, power windows, audio system, and dashboard controls. Higher load paths such as blower motor or rear defogger use larger ratings like 25A or 30A, located in reinforced positions within the panel.

Locate the interior panel beneath the driver-side dashboard and use the printed cover map to match each slot with its assigned circuit before removal. Check amperage ratings like 10A, 15A, 20A, and 30A to ensure correct replacement.
The underhood power distribution center sits next to the battery and handles high-load systems. It includes relays and larger protection links for components such as cooling fan, ignition, and fuel pump. The layout on the lid shows exact positions for each circuit.
Engine bay circuit assignments
Common high-current circuits include radiator fan motor, headlight supply, ABS module, and charging system. These positions often use higher ratings and square relays that control switching under load.
Inside the cabin, lower load circuits manage accessories and control modules. Typical assignments include power windows, interior lighting, radio unit, and instrument cluster. Each slot is labeled with a short code for quick reference.
Testing and verification
Use a multimeter or test light to check continuity across terminals. A broken metal strip or no signal confirms failure. Turn ignition off before removal, install a matching rated component, and test the related system immediately after replacement.
Interior fuse box layout for Jeep ZJ with labels and amperage values
Remove the lower dash cover on the driver side and read the slot chart printed on the back to identify each circuit before pulling any component. Match amperage values such as 10A, 15A, 20A, and 25A exactly to avoid electrical faults.
The cabin-mounted panel distributes power to control modules and interior accessories. Each position is labeled with short codes that correspond to specific systems, allowing quick fault tracing without disassembling additional parts.
Typical labeled circuits
Common slot assignments include:
- RADIO for audio unit
- CLUSTER for instrument panel
- PWR WND for window motors
- INT LAMP for cabin lighting
- WIPER for front wiper motor
Higher load accessories like blower motor or power seats use larger ratings and are positioned in reinforced slots. These often range from 25A to 30A and sit closer to the center of the panel for stable contact.
Use a test light or multimeter to check both terminals of each slot. Power should be present on both sides when active. A missing signal or broken internal strip indicates a failed component.
Handling and replacement steps
Turn ignition off, remove the part with a plastic puller, and insert a matching rated unit firmly into place. Avoid loose seating, which can cause intermittent contact and overheating.
Reinstall the cover securely and verify operation of all related systems such as switches, lighting, and dashboard indicators after replacement.
