Who this is for
Focused support at the right project stage
For EV conversion workshops, classic restorations and specialist prototypes that need a complete loom, a defined subsystem harness or replacement for temporary and undocumented wiring.
Specialist EV engineering
Custom Wiring Looms for EV & Specialist Vehicles
Clean, documented vehicle wiring designed around the installation, environment and future service needs.

What makes a custom vehicle wiring loom serviceable?
A serviceable loom has defined circuits, suitable wire and protection, correct connectors, secure routing, clear labels and documentation. It is designed around load, environment, access and diagnostics rather than assembled as temporary point-to-point wiring.
What VASS can help with
Defined engineering scope
- Circuit architecture, load assessment and protection
- Low-voltage power distribution, controls and auxiliaries
- CAN, sensor, dashboard and charging-interface wiring
- Manufacture, installation support, labelling and documentation
Common problems solved
From uncertainty to a clear next step
- Temporary wiring that is difficult to fault-find or reproduce
- Voltage drop, poor earthing or unreliable connectors
- Harnesses exposed to heat, movement, moisture or abrasion
- New EV systems that do not integrate cleanly with original vehicle circuits
Frequently asked questions
Useful answers before an enquiry
A few clear answers to help you decide whether VASS is the right fit before getting in touch.
Can VASS build only part of a vehicle loom?
Yes. A defined harness for a battery, charger, dashboard, control system or other subsystem can be scoped separately.
Will the loom be documented?
Documentation is treated as part of a serviceable result and is agreed to suit the project scope.
Can an existing loom be improved?
Yes. VASS can review, diagnose and rework an existing installation where that is more sensible than complete replacement.
