Quick answer
What is involved in rewiring a classic car?
It depends on the car, its condition and what the owner wants. A rewire may replace the whole loom or selected sections, and often uses a fuse and relay arrangement so high-current loads run through relays rather than through the switches. Wired Right in Albion Park Rail takes on classic car rewires and custom looms as selected jobs, subject to assessment. The vehicle is inspected first, and the quotation will identify the work and any reports or wiring diagrams included.
Older wiring can deteriorate with age and heat, and many classic and custom vehicles have been modified over the years. A rewire or new loom replaces tired or altered wiring with a planned layout, with fusing and relays to suit the loads on the vehicle.
Custom wiring, full rewires, new looms, classic car rewires and selected engine-conversion wiring are taken on as selected jobs, subject to assessment. Our part is the electrical work: the wiring, looms, fusing and switching. We inspect the vehicle and discuss what you want, and the quotation will identify the work and any reports or wiring diagrams included.

What this covers
Classic car rewires
Full or partial rewires on selected classic vehicles, subject to assessment, with fusing and relays planned for the loads.
Custom looms & new harnesses
New looms built to suit the vehicle on selected jobs. How and where the harness is built depends on the job and is set out in the quotation.
Engine-conversion wiring
Wiring for selected engine conversions, considered case by case: adapting the engine harness and integrating it with the vehicle’s ignition, gauges and other circuits where the parts and information allow.
Custom build wiring
Wiring for hot rods and other custom builds, planned around the build, on selected jobs.
Fuse & relay panel installation
Fuse and relay boxes fitted and wired with labelled circuits as part of a rewire or new loom.
Switch wiring
Switches wired through relays where the load requires it, so the switch carries a control signal rather than the full load current.
How the job runs
- 1
Inspect and assess
The vehicle is inspected and the job assessed before it is accepted. Some existing wiring and faults need testing before an estimate can be provided.
- 2
Plan the circuits
Loads, fusing, relays and cable sizes are planned before work starts, to suit the vehicle and the equipment fitted.
- 3
Build and install
The loom is built and installed as set out in the quotation, including whether it is built off the vehicle and whether circuit numbering or a wiring diagram is included.
- 4
Test circuit by circuit
Circuits are energised and checked individually before the vehicle is handed back.
Custom Electrical Work: common questions
How long does a full classic car rewire take?
It depends on the car, how much of it is apart and how much wiring is being replaced. We can give an indication after an inspection, and the quotation will identify the work included.
Can the car keep an original look?
In some cases, depending on the car, the parts available and the work proposed. Options such as period-style cable, retaining original switchgear and mounting a fuse and relay panel out of sight can be discussed during the assessment. We will confirm what is proposed before work is authorised.
Do you do engine conversion wiring?
Selected engine-conversion wiring jobs may be considered, assessed case by case. The work is the electrical side only: adapting or building the engine harness and integrating it with the vehicle’s ignition, gauges and other circuits. Whether a particular conversion suits depends on the engine, the vehicle, the parts supplied and the information available.
Why does my classic dim its headlights at idle?
There can be several causes, including voltage drop through the switch, connections or earth path, worn connections, or low charging output at idle. Testing shows which applies. Where voltage drop through the switch or earth is the cause, moving the load onto a relay and improving the earth path may help.
Will I get a wiring diagram?
Wiring diagrams and circuit labelling are provided on certain jobs or on request. The quotation will identify the work and any reports or wiring diagrams included.
