one last question (for the next 30 seconds )

With the 07=08 mod, all we are doing to shorting pin 40 on the ECU to ground to turn on the CS and then short it to ground with a load (~600 ohms) to set the CS..

Or did I miss something?

That's all that's to it. See if your sedan has a wire already in pin 40. If so, you can tap it way up under the dash (per the discussion buried in that thread), or at least tap it somewhere along the line.

Ok. The next dumb question. Where is the ECM??????

if you are standing in front of the car looking at the engine bay, it is attached to the firewall in the upper left corner
