Design the circuit.
Build the harness.

01 / SCHEMATIC

Start with the circuit.

Connect devices, define pin functions and trace the electrical design. Power, grounds, twisted pairs and named circuits stay visible in one schematic.

Electrical schematic linking a PDM, battery isolator, battery, keypad and FT550, with coloured conductors, CAN twisted pairs and lighting circuits.

02 / 2D HARNESS

Transform the schematic
into a 2D harness.

Turn the circuit into a dimensioned harness layout. Arrange connectors and terminals, shape the branches and label the destinations.

03 / INSIDE THE BUNDLE

A look inside the bundle

2D harness branch with white covering, connectors C10, C11 and C12, terminals T13 and T14, branch fittings and length dimensions.

The same 2D branch with coloured conductors exposed between C10, C11 and T13, and junctions CP20, CP21 and CP24 highlighted.

04 / 3D HARNESS

Bring your harness to life
in the 3D designer.

Place components in 3D space and route the wiring harness between them. Import reference CAD models to achieve an accurate design the first time.

The same 3D assembly with the chassis hidden, revealing the complete harness and its lights, fan, battery and control components.

3D harness routed around the white tubular chassis, with lights, fan, battery and control components in position.

One branch. Three ways to inspect it.

Coverings, wires and junctions are modelled in 3D space, ensuring issues are found at the design stage instead of the production stage.

Covering on Covering off Wire selected

3D lamp branch with black covering, moulded branch boots, red identification sleeves, connector housings and a ring terminal.

The same 3D lamp branch with covering and chassis hidden, exposing coloured conductors into two connectors and a ground ring terminal.

05 / SPLIT PANES

Split pane design

View each pane side by side for easy cross-referencing.

Schematic + 2D Schematic + 3D

Side-by-side schematic and 2D harness with the Left Indicator circuit highlighted yellow in both panes; the selection shows 16 AWG and 608 mm.

06 / CONNECTIONS

Every wire.
From end to end.

Review conductor IDs, wire colours and gauges alongside their endpoints, circuit names and lengths.

From a connector cavity to a junction, the connections list brings the electrical and physical details into one searchable view.

Connections table with conductor IDs, colours, gauges, part numbers, from and to endpoints, net names and lengths, including the Left Indicator at 608 mm.

07 / PARTS LIBRARY

A growing global library

Choose from an expanding list of parts in the global library, or remain completely offline with your own local library.

Parts library with global, local and project sources, searchable categories and manufacturer details; this project is selected with a Phoenix Contact ring terminal preview.

Upload STEP files of your components

Add a 3D model to your part, define the connector’s cavity designations and configure its contacts and accessories.

AT06-12SA connector part editor with manufacturer details, twelve numbered cavity designations, a STEP model preview and a base configuration listing contacts and an accessory.

Create connector assemblies

Inspect the housing and its accessories together in 3D.

3D preview of the AT06-12SA connector assembly, showing the grey housing, red cavity face and turquoise lock, with AT06-12SA housing and AW12S lock listed as assembly parts.

08 / PARTS

Know what goes
into the harness.

Bring connectors, terminals, wires and other project parts together with their manufacturers, quantities and costs.

See which parts are included, which are unused and which components still need a part assigned.

Grouped project parts table with manufacturers, quantities, unit prices and totals, plus Included, Not used and No part status labels.

09 / DOCUMENTATION & EXPORT

Export Documentation

Export embeddable HTML, PDFs, Excel spreadsheets and videos to share your design and build documentation.

Documentation workspace with a draft C1 pin-out sheet showing a wire-side cavity diagram, housing details, 3D connector preview and pin table, alongside the document page tree and Export button.

10 / LIVE DIAGNOSTICS

Real-time diagnostics.
Better fault-finding.

Store the LoomView file on the PDM for easier maintenance and diagnostics later on. See live output states, voltage and current alongside your wiring design, and trace circuits through the schematic, 2D and 3D harness.
