Depending on the model year (typically split between pre-restyle 2001–2010 models and post-restyle 2011–2015 variable nozzle turbo models), the ECU utilizes either a or 5-plug configuration. These connectors are designated alphabetically (e.g., Connector A, B, C, D, E) or numerically. The pins are split into three primary functional groups:
