This is an old revision of the document!
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 into the ECU connectors on the ECU itself, with the male pins pointing out at you. The diagrams do not 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.
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.
