Link G4X for your Subaru WRX V10 EJ25

Bring your car up to date with the latest technology with one of the best freely programmable control devices! The Link G4X can be installed without making any changes to the standard wiring harness, hiding in the original housing and offering a variety of new possibilities.

Thanks to many expansion options, every parameter can be monitored and output with the Link G4X. Displays can also be connected, making inaccurate and sluggish additional displays unnecessary.

This control unit is developed for the WRX V10 with EJ25 engine. This ECU therefore covers the model series with EJ25 from 2004 to 2007.

- This ECU WRX104 primarily covers the 2004-2006 vehicles
- The ECU WRX107 primarily covers the 2007 vehicles (listed separately)

However, the second ECU variant WRX107 is required for some 2006 vehicles.

The quickest and most reliable way to determine this is to check how pins A1-3 are populated.

If the pins have wires, ECU WRX104 is required. If there are no cables, ECU WRX107 is required.

Suitable for vehicles from the GG or GD series with e-gas. Not suitable for the GR/GH/GE/GV Hatchbacks or 3rd Gen WRX.

Only for vehicles with manual transmission. Please compare the pictures of the plugs with your original control unit and the previous description of the different versions.
