I ran into some electricity issues in our apartment and now I need to remove the PSU from the miner again, but the "Power control wire" http://puu.sh/A5Ju6/8173b79b26.png is stuck.

How in the world do you get this off again? It's so tight down there, I can't get a proper grip with my fingers on it. I don't know what to do with this upstanding stick that is part of the miner - or how else you are supposed to use this cable. I tried pulling it gently with tongs and bending the plastic forward and backward a bit, with a tiny screwdriver whilst pulling, but the cable just remains as stuck as always.
