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.
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.Anyone know where the ECU is on an 05 STS Wagon?
