I wouldn't flame for this post, to be honest.
He tried to search. We all know the information is here, but the location isn't as easy to find as you might think. Shifty found it because he knows where to look, not how to manipulate the search engine.
He used a meaningful thread title.
He explained what he needed it for, and what steps he had already taken to try to find it.
He posted all the required relevant information.
This is how to get your questions answered. Even if I didn't know the answer off the top of my head, I'd be willing to do some research to help this guy. Of course, I don't have to, because he got an answer in 39 minutes, probably because he asked in the right way!
PS: The reason your searches didn't find what you needed is due to a limitation on length of search terms. Anything under 4 characters gets ignored. The easy workaround for this is to make your short words longer by adding a wildcard to the end - so ECU becomes ECU*, for instance.
