Link G4X Toyota TST205X Plug-In ECU – MR2 SW20 Rev2-3 / Celica ST205

The Link G4X Toyota TST205X Plug-In ECU gives you modern standalone engine management while retaining the convenience of a genuine plug-in ECU.

Designed for the Toyota SW20 MR2 Rev2-3 and Toyota Celica ST205 with 3S-GE or 3S-GTE engines, the TST205X fits directly into the factory ECU location using the original wiring loom and ECU connectors.
