<h1>ECU Wiring Information</h1> <div class="level1"> <p> This page contains basic wiring information for the ECU connector in a 1G and 2G DSM. Please note that the diagrams are all shown as you are looking <b>into</b> the ECU connectors on the ECU itself, with the male pins pointing out at you. The diagrams do <b>not</b> illustrate the wiring connectors in the car. Many people will assume the diagrams show you looking "into" the wiring connectors in the car. But this is not correct. </p> <p> Some tips on reading the MFI schematic docs will be collected on <a href="/wiki/doku.php?id=mfiio" class="wikilink1" title="mfiio">this page</a>. </p> </div> <h1>1G ECU/MFI</h1> <div class="level1"> <p> The document linked to below contains pin numbers and wire colors for the 1G ECU connector. Thanks to Jeff Hanko for the first version of this document and for getting us started on a long overdue effort. </p> <p> <a href="http://www.dsmlink.com/images/forums/1GECUPinout.pdf" class="urlextern" title="http://www.dsmlink.com/images/forums/1GECUPinout.pdf" rel="nofollow">http://www.dsmlink.com/images/forums/1GECUPinout.pdf</a> </p> <p> The following is a copy of the MFI wiring schematic taken from Mitsubishi's own shop manual documentation.

This document was provided by the kind folks at <a href="http://www.evocoupe.net/forum/" class="urlextern" title="http://www.evocoupe.net/forum/" rel="nofollow">evocoupe.net</a>. </p> <p> <a href="http://www.ecmtuning.com/images/forums/EVO1-3ECUPinout.pdf" class="urlextern" title="http://www.ecmtuning.com/images/forums/EVO1-3ECUPinout.pdf" rel="nofollow">http://www.ecmtuning.com/images/forums/EVO1-3ECUPinout.pdf</a> </p> <p> The following is a copy of the MFI wiring schematic taken from Mitsubishi's own shop manual documentation. Provided here for references purposes only. </p> <p> <b>NOTE:</b> The MFI circuit diagram below is NOT the EVO1-3 diagram. I've searched LONG and HARD for the EVO1-3 circuit diagrams, but have failed to find them *anywhere*. I've even asked a couple guys over in Japan to source them, but everything has fallen through. So we're left with EVO4 diagrams which closely match the EVO1-3 with the exception that there's an extra connector and that pins 71-92 in the EVO4 diagrams should be remapped to 51-72 to match up with the ECU pin out provided above. </p> <p> <a href="http://www.ecmtuning.com/images/forums/EVO4MFI.pdf" class="urlextern" title="http://www.ecmtuning.com/images/forums/EVO4MFI.pdf" rel="nofollow">http://www.ecmtuning.com/images/forums/EVO4MFI.pdf</a> </p> <p> If anybody can source the TRUE Japanese EVO1-3 shop manuals with circuit diagrams, the entire rest of the world would appreciate it! As far as I can tell, nobody has these. </p> </div>
