Schematics View
The Schematics View automatically generates a clean, professional electrical schematic from your harness design. It traces every wire connection from the selected component outward, rendering each connection chain as a horizontal wire diagram with device boxes, pin labels, connector gender icons, and wire colors — all without any manual drawing.
Select any component in the Device Tree to render its schematic. The view centers on that device and draws all wires going out from it toward connected devices.
1. Reading the Schematic
Each row in the schematic represents one wire connection. The layout is:
[Selected Device] ─── wire ─── [Connected Device]
- The selected component is drawn as a wide block in the center-left.
- Connected devices appear as smaller blocks to the right or left depending on their position in the chain.
- Pin labels appear above the wire at each device edge, formatted as
ConnectorName:PinNumber(e.g.MaxxECU 1:M1). - Wire colors are rendered using the actual hex color defined in your project — including stripe patterns for two-tone wires.
2. Pin Function Tooltip
When you hover your cursor over any wire segment, a tooltip appears showing the pin's assigned function name.

What is shown:
| Field | Example |
|---|---|
| Pin label (connector + pin number) | MaxxECU 1:M1 |
| Pin function name | Injector 3 |
The pin function name comes from the pin definition in the Component Library. When a pin has a function assigned (e.g. Injector 3, 12V Power, CAN-H), hovering the wire shows it instantly — without needing to open any panel.
When a pin has a function assigned, the cursor changes to a help cursor (❓) as you hover over the wire, indicating that more information is available.
The tooltip disappears as soon as you move the cursor off the wire. If a pin has no function assigned in the library, no tooltip is shown and the cursor remains unchanged.
3. Connector Gender Icons
Each pin label is accompanied by a small gender icon drawn at the device box edge, indicating whether the connector at that pin is male or female.
| Icon | Gender | Meaning |
|---|---|---|
▶ (filled square with pin) | Male | This side has a protruding pin contact |
⊂ / ⊃ (open cup arc) | Female | This side has a socket/receptacle contact |
The gender is read from the connector data in your project. Icons appear inside the device box, directly at the edge where the wire terminates, so the schematic remains compact and readable.
4. Navigation
The Schematics View supports full pan and zoom, matching the Canvas experience:
| Action | Result |
|---|---|
| Scroll wheel | Zoom in/out centered on the cursor |
| Ctrl + Scroll | Fine-grained zoom |
| Click and drag | Pan the view |
| Zoom to Fit button | Re-centers and scales the view to show all connections |
5. Exporting to PDF
You can export the schematic as a PDF directly from the view.
- Export Current — exports the schematic for the currently selected component.
- Export All — iterates through every device in the project and generates one PDF page per device.
Exports include an engineering title block with the project name, device name, page number, and version history. Pro accounts export without a watermark.
Free-tier exports include a Wiringly watermark. Upgrade to a Pro plan to remove it.
6. Branch Stubs
When a wire routes through a splice or branches to multiple endpoints, branch stub lines are rendered to indicate the junction point. These can be toggled on or off using the Show Branch Stubs control in the toolbar.
7. Cable Shielding
If a wire belongs to a shielded cable, the schematics view draws a dashed bounding rectangle around all conductors in that cable and labels it SHIELD. Individual shield drain wire terminations are also shown with their connector and pin labels.
