Bench Tune Wiring

[askoncemore]

I have been having trouble uploading my tunes using my X4.  The last two uploads locked my PCM and it needed to be sent into SCT. 

So....

They recommended that I run a bench tune setup. (example here: https://www.youtube.com/watch?v=go6AksH45II )

Does anyone have the wiring diagram for the OBD-II port to go directly to the PCM?

Thank you in advance.
