My Roof Cable Route: Junction Boxes, Labels and Fish Tape
My camper van roof cable route in seven build photos: junction boxes, cable glands, wire labeling, fish-tape pulling and the entry into the van.
Build Guides
Choose a reading path through electrical and solar references, then keep the source and open questions with your own build notes.
Before comparing component drawings, use the daily energy budget and solar-sizing guide to record loads, solar assumptions and possible shortfalls. The blank energy-budget CSV keeps your inputs separate from the worked example.
For the installed components and decisions in my Ford Transit, start with my camper van electrical system, then use the references below for a specific question.
Use this route to choose a reference before collecting the details for your own build. The library includes archived diagrams, explanations and vehicle-specific material. A reading path does not select a complete electrical system or establish that an example applies to your van.
Use the wiring-diagram reading reference to locate the symbols and legend you need to understand. Keep the original drawing, source and equipment names together. Write down what remains unclear before treating the drawing as a parts list.
Follow the solar-panel ratings guide, then the series-versus-parallel comparison. Keep the actual panel and controller documentation beside your notes. Use the references to identify questions to check, rather than copying a pictured arrangement into a purchase list.
The DC wire-sizing guide organizes equipment instructions, cable-run measurements, chart assumptions and protection checks. The archived electrical charts provide supporting references. Record the source and units for a value instead of choosing a cable or fuse from an isolated picture.
Keep the model year and document identity with vehicle-specific notes, such as the 2023 Ford Transit ground-point reference. Mark any mismatch or missing documentation as unresolved. Return to the relevant equipment and vehicle instructions before carrying a reference detail into your own plan.

Discover the truth about cooling LiFePO4 batteries in camper vans during hot summers.
Continue with the relevant original collection or detailed reference below. Check each source’s vehicle, equipment and publication context before applying it to your own build.
Write one unresolved question, the exact equipment or vehicle it concerns, the source you need and the evidence that would close the check. Keep assumed values distinct from measured or documented ones. If a change affects the layout, drawings or purchases, use the decision log and blank worksheet to record those dependencies.
Use the planning worksheet directory for vehicle, layout, cost, change and maintenance-access records. For measurement and layout tasks, return to the planning and tools reading route.
