Get a ECU Patch/Extension Harness, I just wished someone would have told me about that before I did the work on my car (AEM have some availlable).
If you get a RRM ECU second hand, it`s a good deal, but make sure you get the fuel map that comes with it. I was unable to get any help from RRM on mine.
