Dell Precision Tower 3620 - Front USB 3.0 I/0 header pinout

Hi, I'm wondering if anyone can provide me with a pinout for the front USB 3.0 header. I installed a GPU that's so large that the header is completely covered up, and I cannot install the front I/O cable. Without the cable, the system gives you an error message that does not allow the machine to boot. I'd like to short the Front I/O Cable Detect pin (if it has one) to ground. The plug looks like this:

In addition to the detailed information from @redxps630 would an adapter such as this one at Amazon help (I cannot tell from the picture).

@JOcean​ Thank you for your reply, unfortunately there is no physical space under there for even an adapter that is as small as that one.

@redxps630​ Thank you, I think you are correct. It doesn't seem to have a specific pin to sense whether a cable is connected, so I'm not sure if something could be grounded to trick the bios into thinking that the cable is installed.

@gravyishot​ Have you tried disabling the USB port in the BIOS?
