Haltech Nexus T1 T2 Harness – Basic Universal Wire-In Harness

Building a custom engine harness for your Haltech Nexus T1 or Nexus T2 ECU? The Haltech Basic Universal Wire-In Harness provides the starting point for a clean, professional custom installation.

Designed specifically for the Nexus T1 and T2, this harness provides 2.5 metres (8.2ft) of unterminated, automotive-grade TXL wiring, allowing your installer to route and terminate each connection to suit your specific engine and vehicle.

Every wire is colour coded and clearly labelled, taking the guesswork out of identifying ECU circuits during installation.

Haltech Nexus T1 TS Harness – Designed for Custom ECU Installations

Unlike a plug-and-play harness designed around one particular vehicle or engine, the Basic Universal Wire-In Harness gives your installer the freedom to build the engine harness around your application.

It’s ideal for:

• Custom engine conversions
• Modified street cars
• Race and competition vehicles
• Restomods
• Custom-built vehicles
• Engines without a dedicated Haltech plug-and-play harness
• Rewiring an existing performance vehicle

The unterminated design means connections can be routed and terminated where required rather than adapting a harness originally designed for another application.

Haltech Nexus T1 TS Harness – Why Use a Universal Wire-In Harness?

For engine conversions and heavily modified vehicles, starting with a universal harness can often produce a cleaner result than trying to adapt an existing factory or plug-and-play loom.

The 2.5m harness length gives the installer flexibility when determining ECU location and wiring routes, while the labelled circuits make it easier to identify and terminate each connection correctly.

The result is a harness that can be built specifically around the engine bay, sensor locations and electrical requirements of your vehicle.
