Exclamation OBD II port shorting out with tuner plugged in.

I have a tunner that plugs in to my OBD II port. The problem is that now my OBD II harness is shorting out and I don't know why. I know it is not the power block for the tuner because I have used 2 different blocks both brand new and it is doing it with both of them. I moved the wires in the back of the harness and noticed the pins were moving as well. Does anybody know how to and where to get a replacement harness and how it goes together? Any thing helps thank you very much.
