Elite 1000/1500 Subaru WRX MY99-00 Plug 'n' Play Adaptor Harness (HT-140822)

Put a Haltech Elite 1000/1500 in a GC8 WRX (MY99-00) without cutting a single factory wire.

The Haltech Elite 1000/1500 Subaru WRX MY99-00 Plug 'n' Play Adaptor Harness sits between the factory engine harness and a Haltech Elite 1000/1500 ECU. One side carries the factory ECU connectors, the other plugs straight into the Elite, so the factory loom stays untouched and the swap is fully reversible. A typical install is a few hours, not a weekend of pinouts and splices. It suits the MY99-00 WRX (Australian-delivered and JDM) with a manual transmission.

Need the ECU as well? The same application is also available as: Elite 1500 ECU kit (HT-150943).
