Custom Wiring Harnesses

Custom wiring harnesses are what we do best. From engine harnesses for ECU installs to full chassis rewires, we design and build harnesses in-house at our Clontarf workshop to suit your car, your parts and how you'll use it.

How a harness build works

Consultation. We talk through the build and help you choose the ECU, dash, power management and sensors.
Measure-up. We measure the car so the harness fits your layout. Mobile measure-ups are coming soon.
Design and build. The harness is planned and built in our workshop.
Install and commission. We fit it, check every circuit and get the car ready to start.
Tuning, your choice. Happy for us to tune it? We can tune it on our dyno. Got your own tuner? We'll hand it over wired, commissioned and ready for them.

Choosing parts?

See ECU installs for help picking an ECU, or browse engine management and driver displays.
