WRXLink (V10) WRX107X

Description

The WRX107X fits inside the factory enclosure and replaces the OEM ECU of V10 WRX cars with the EJ25 engine and electronic throttle, with no alteration to the wiring loom.

Choose the right model with the pin check: look at pins A1–A3 on the OEM connector. If they are empty, you need the WRX107X (this listing, 225-4000); if they have wires, you need the WRX104X. The WRX107X covers 2007 and some late-2006 cars, so this check is essential.

G4X Plug-In ECUs replace the factory ECU and fit inside the original enclosure, with no alteration to the vehicle wiring loom. All the features of a Link G4X wire-in ECU, with a direct-fit installation.
