Supplied as: only naked PCB.
The Subaru 135 Superseal adapter connects the four-section 135-pin vehicle harness to 60-pin, 34-pin and 26-pin Superseal connectors. It routes 110 contacts.
- Subaru Impreza WRX / WRX STI with the 135-pin ECM connector: intended application. The vehicle pinout follows the 2013 WRX EJ255 reference with SI-Drive. Check the specific harness before installation; compatibility across the previously listed 2011–2021 range has not been established.
- 2017 WRX STI EJ257: use the STI references to check differences. Contact 6-4 is part of the neutral-position switch circuit, whereas the 2013 WRX pinout identifies it as ground. Do not ground it or close JP3 for that STI circuit. Starter wiring also differs between key and push-button versions.
