Multi-Layer Harness Design

Wiringly supports designing complex harnesses across multiple layers. This functionality is intended for organizing large vehicle looms by separating sections like the engine bay, chassis, or interior into their own distinct workspaces, while maintaining electrical continuity throughout the entire project.

[!TIP] This Chapter 4 walkthrough demonstrates how to use the Bundle tool to define the physical path of your harness and shape it for a 1:1 Formboard layout.

Harness Bundling Walkthrough

Layer Management​

You can switch between different layers using the layer control panel on the canvas. The default base layer contains the primary harness layout.

Layer Control Panel

  • Adding Layers: Create new layers to house sub-harnesses or specific electrical sections.
  • Active Layer: Any components placed or routing modifications made will only apply to the currently active layer.

Inter-Layer Connections​

Harness segments can be connected across different layers using bulkhead connectors or direct mating links.

Intelligent Signal Tracing​

Electrical signals automatically trace recursively through mated connectors and inter-layer links. Selecting a wire or pin on one layer will show its ultimate logical destination (e.g., a specific ECU pin or splice) even if that destination resides on a completely different layer.

Layer-Aware Routing and Measurements​

Physical routing and bundle measurements are managed independently per layer.

  • Modifying Measurements: Editing bundle lengths directly on any layer intelligently handles geometry updates and repositioning of connected sub-trees within that specific active layer context.
  • Persistence: Component positions and routing paths are saved securely for each layer. This allows for maintaining a clean base layout while simultaneously optimizing the detail of each individual layer.
