Haltech Elite 2500 / Elite 2500T Premium Universal Wire-In Harness | 2.5m (8ft) | Includes Haltech Moulded Fuse Box

The Haltech Elite 2500 / Elite 2500T Premium Universal Wire-In Harness is a complete, universal main wiring harness engineered for use with the Haltech Elite 2500 and Elite 2500T ECU platforms — providing the core power, ground, and ECU interface wiring required for a complete Elite 2500/2500T installation in any vehicle application. At 2.5m (8ft) in length, the harness provides sufficient reach for the majority of engine bay installations. The Premium Universal Wire-In Harness includes Haltech's moulded 6-circuit fuse box with lid, 4 relays, 7 fuses, and pins for the 2 spare power circuits — a complete power management solution that eliminates the need to source a separate fuse box for the Elite 2500/2500T installation. Haltech is one of the most respected standalone ECU brands in the performance aftermarket — an Australian brand with over 35 years of ECU development experience trusted by professional tuners and serious performance builders globally.

Key Features:

• Universal wire-in harness — universal main harness for the Haltech Elite 2500 and Elite 2500T ECU — correct for any vehicle application where the Elite 2500/2500T is being installed
• 2.5m (8ft) length — sufficient harness length for the majority of engine bay installations — verify that 2.5m is sufficient for your specific vehicle's ECU mounting location and engine bay dimensions before ordering
• Haltech moulded 6-circuit fuse box — includes Haltech's moulded 6 power circuit fuse box with lid — a clean, purpose-built fuse box for the Elite 2500/2500T power circuits — eliminates the need to source a separate fuse box
• 4 relays included — 4 relays for the main power circuits — correct relay count for the Elite 2500/2500T's primary power management requirements
• 7 fuses included — 7 fuses for the fuse box circuits — correct fuse count for the 6 primary power circuits plus one additional
• Pins for 2 spare power circuits — pins included for the fuse box's 2 spare power circuits — allowing additional circuits to be added for auxiliary power requirements (fuel pump, cooling fan, etc.)
• Firewall grommet included — firewall grommet for clean, sealed harness routing through the firewall — correct for installations where the ECU is mounted in the cabin and the harness routes through the firewall to the engine bay

Universal Wire-In Harness — What It Is and What It Requires:

This is a universal main wire-in harness — it is not a plug-and-play harness for any specific vehicle. The Premium Universal Wire-In Harness provides the core power, ground, and ECU interface wiring for the Elite 2500/2500T installation — but a complete Elite 2500/2500T wiring installation requires additional wiring for all engine sensors, actuators, ignition, injection, and other engine management functions. The universal harness is the starting point for a custom Elite 2500/2500T installation — the installer will connect the harness to the vehicle's engine sensors, actuators, and electrical system using the correct wire gauges, connector types, and circuit assignments for the specific engine and vehicle application. This harness is correct for custom engine builds, engine swaps, and any application where a vehicle-specific plug-and-play harness is not available. Professional installation by an experienced ECU installer and automotive electrician is required.

Elite 2500 vs. Elite 2500T — Harness Compatibility:

This harness is compatible with both the Haltech Elite 2500 and Elite 2500T ECU variants. The Elite 2500 and Elite 2500T share the same main harness connector configuration — the difference between the two ECUs is the Elite 2500T's additional traction control inputs and outputs, not the main harness interface. Verify your specific Haltech Elite ECU variant before ordering.
