Anyone know where the ECU is on an 05 STS Wagon? Bought the wagon recently and I am trying to find where the DP Chip is and can't seem to locate it. It seems the ECU is located in a million different places dependant on model.

On top of the trans tunnel, in front of the ash tray. (in front towards front of vehicle), does that make sense? sounds a bit weird

The ECU should be just behind the heater controls. In most cases I've seen, the DP Chips are fitted in the engine bay because they get wired to the fuel pump harness.

Dont get mixed up with airbag module,with yellow plugs. That lies horizontal, I think ECU stands vertical.

The DPchip is not connected to the ECU, it's connected to the fuel rail under the intercooler (firewall side). Find the connector and follow the wiring loom.
