The wiring behind a clean build.

Harnesses, interfaces, cabling and the bits that make installs clean — the groundwork that keeps a system reliable, quiet and built to last.

What we do

Every wire, done properly.

The harnesses, interfaces and cabling that turn parts into a proper system.

Plug-&-Play Harnesses

Vehicle-specific harnesses for a tidy, fully reversible install.

CANBUS & SWC Interfaces

Keep steering controls, chimes and data working as standard.

Power & Big-3 Upgrades

Heavier power, ground and charging cable so amps get the current they need.

Amp & Sub Wiring Kits

Correctly sized power, ground and signal cabling for the gear.

Fusing & Distribution

Proper fuses, blocks and distribution so the install is safe.

Connectors & Terminals

Crimped, soldered and sealed for a connection that lasts.

Built for custom installs

Wiring worthy of the build.

What proper wiring actually gives you.

Clean Looms

Loomed & routed

Wiring bundled, hidden and routed so the install looks factory — or better.

Reliable Power

Sized & fused

Correct gauge, grounding and fusing so nothing browns out or overheats.

Future-Proof

Serviceable

Labelled, accessible wiring that’s easy to add to or service later.

How it works

Plan, route, terminate, test.

The method behind a loom that lasts.

01

Plan

We map the system, current draw and the cleanest cable routes.

02

Route

Power, ground and signal run separately for a quiet, tidy loom.

03

Terminate

Every joint crimped, soldered and sealed to a proper standard.

04

Test

Voltage, grounds and every retained feature checked before handover.

Common questions

Wiring & Integration — FAQ.

The questions we’re asked most.

Do you make custom wiring harnesses?+
Yes — from vehicle-specific plug-and-play harnesses to fully custom looms for one-off and show builds, so the install stays tidy and reversible.
Will aftermarket wiring affect my factory features?+
No — we use the correct CANBUS and steering-control interfaces, so chimes, controls, cameras and warnings keep working.
Why upgrade the power wiring (the “Big 3”)?+
Bigger amps draw serious current. Upgraded power, ground and charging cables keep voltage stable so the system performs and your electrics stay healthy.
Which wiring and accessory brands do you use?+
Trusted brands like Connects2, FOUR Connect, Carav, Cyberdyne and 12V Nation — matched to the vehicle and the job.
Can you tidy up a previous install?+
Yes — we re-loom, re-fuse and re-terminate messy or unreliable wiring so it’s safe, quiet and easy to service.

Wire it right.
