Once we’ve confirmed it fits your vehicle, our Fitment Guarantee covers it. If it doesn’t fit, we pay the return freight both ways and refund or exchange it. No restocking fee. How it works
Covered only after we confirm the fit from your rego or VIN. Tell us within 30 days, with the part unused. Special-order, freight-quoted and tune/software items are excluded. Change of mind is different: 30 days, a 15% restocking fee, and you pay the return postage.

Description
Quality terminated wiring from Haltech. We use these harnesses in our own ECU installs, which means proven fitment before it goes in your build.
Overview
If you are using a factory harness and are after an easy ECU upgrade, take a look at Haltech Plug ‘n’ Play Adapter Kits. These adapters plug directly into your Haltech ECU and have a set of factory connectors on the other side which plug straight into the factory harness.
A simple Haltech Plug ‘n’ Play product that allows you to be up and running in just a few hours.
The quick start guide will walk you through installation of the Haltech Plug ‘n’ Play adapter into your vehicle.
Features
- This harness when installed in conjunction with a Haltech Nexus S3 ECU opens the door to virtually limitless performance modification and tuning of your vehicle.
- Fully programmable systems allow you to extract all the performance from your engine by delivering precisely the required amount of fuel and ignition timing that your engine requires for maximum output under all operating conditions.
Note: Haltech products are intended for sanctioned off-road/competition use. Ask our team about compliant options for your application.
