Works, just plugged in wrong.

I hooked this up to my truck and found the tester was flashing the wrong lights. So I thought maybe my truck isn't hooked up properly. But I went and tested another machine at work and found I got exactly the same results. It turns out that BU and RT are reversed. So it still works for at least 7-pin, but it just shows the wrong LED.

Pros
