How early of a build do you have? The earlier the build, the more prone for mistakes. My 9 is an early bulid with numerous mistakes.
For instance, note the position of the horn relay. It's installed upside down. We had a know-it-all whistlebritches a few years back who blew it out of the water, claiming that someone had to have changed it because it would have never come from the factory that way.
The week after he hosed me, he posted a picture of a 9 t/a claiming it was the global benchmark for a exact correct build. He used the picture to as research on something else. Right there in the corner, just like mine, the horn relay was installed upside down. I might potty mouth back on occasion, but I usually let it rest. Because he was such a dick--worse than me!--I called him out a half dozen times, but I guess selective reading came into play.
It's my opinion that PHS is merely a guide for direction, and there are a hell of a lot of mistakes in their information.
