Ecu Wiring Table

When reading pin out diagrams, you are reading them by the back of the connector (where the wires go in). #1 pin (INJ4), is at the top left. To the right of #1 is pin 2 which is INJ3...and so on. Once at the end of the row (going left to right), the following pin begins on the next row at the far left.
