Elite 2000/2500 Subaru GDB WRX MY01-05 Plug ‘n’ Play Adaptor Harness Kit

Bridge to Elite Power for the GDB

The Elite 2000/2500 Plug ‘n’ Play Adaptor Harness is designed to connect a Haltech Elite 2000 or 2500 ECU to the Subaru GDB WRX (MY01-05). This is the harness only, intended for users who already own an Elite ECU and want to install it into a cable-throttle EJ20 platform.

Seamless Connection

This harness plugs directly into the factory Subaru ECU header and terminates with the Elite ECU connectors. It supports all factory functions including the instrument cluster, air conditioning request, and AVCS (where equipped). By using this harness, you avoid the need to cut into the factory loom, making the installation fully reversible and preserving the vehicle’s value.
