Already when I bought the Crossfire it missed one of the jack points. It was a bit difficult to find them in Europe where I live, mostly because it has some confusing names in spare part lists.
I have documented how I found the jack location point and installed. It's a bit confusing, because I didn't order one for a R170 chassi but a R171 chassi. It fit almost perfect.

Maybe to some help for some.
