The Mitsubishi Lancer Evolution has enjoyed a decent run in the US after making it’s debut on American shores in 2003. And ever since the Evo has certainly been one of the hottest sport compact import vehicles that money could buy.
The 4G63 underwent several small changes from the previous generation to this iteration, namely the flipping of the motor and transmission. This switch enabled Mitsubishi’s engineers to beef up the AWD transmission, something that had been one of the weaker links in previous Evolutions.
Whether you are installing a boost gauge, boost controller or intercooler kit on your Evolution, chances are if your devices need power, you’ll need this wiring diagram of the ECU. If you have any questions about our Mitsubishi Evolution VIII ECU Pinout, please leave a comment below.
