The ECU PCB fits discretely inside the original factory enclosure.

Installation of Link’s Subaru WRX104X ECU is simple — no alteration of the factory wiring loom is required.
A built-in connector (or pins in some models) provides additional inputs and outputs such as oil pressure inputs or anti-lag / logging switches.

Factory features are supported – see Features for any exceptions.
