Easy to install. Affordable. Reliable. The Link G4X PlugIn ECU transforms your WRX into a precision-tuned performance machine. Enjoy the latest in engine management technology, fitted directly into your OEM enclosure with no loom modifications required. Choose the Right Model – Pin Check Required! The fastest and most reliable way to determine which ECU you need is to check pins A1–A3 on the OEM connector: If pins A1–A3 have wires → You need the WRX104X. If pins A1–A3 are empty → You need the WRX107X (this listing, 225-4000) Some late 2006 cars require the WRX107X, so this check is essential.
