The big table…
June 10, 2007
Here’s the table I’ve been working from. This table maps every 2004 STi ECU wire to every RS ECU wire (except for the couple engine to elsewhere wires). This also includes which wires will be blended from the RS harness into the STi harness. There are a couple question marks, particularly about the main relay. I’m almost set on buying another 2000 RS ECU, pulling the plugs, and doing all the blending between the RS ECU plugs and the STi harness so I don’t have to cut anything in the RS.
