where can we get parts to repair a WMR controller, I need a 25pin ribbon cable

It’s not really an answer and you probably already checked this but the ribbon cable has an arrow. I thought I broke my ribbon cable when I freed a loose screw jamming the trigger (great job Dell), but in reality, I just put the ribbon cable in backwards. Probably not the case with you, you probably didn’t make my mistake, but just in case.

The ribbon cable is ripped, The person that I got it from, opened it and ripped the cable. It has to be replaced. Thank you though.
