Does anyone have any ideas how to get this off? Pliers maybe? There is a harness that connects to a control unit on the gas pedal. I'm trying to remove that harness however, room is incredibly tight. There is little red slider (i'm guessing) lock. I can slide it up but that harness seems to not want to move. as far as i can feel, because there is no way to see behind the harness there is no other locking mechanism on the other side.

I bought a Weapon-R throttle controller (damn jap sweatshop work, i'm sure) and its plug in play right into the OBDII harness and the throttle control unit on the gas pedal...OBDII connection=Easy Pedal connector=No room and seems to be practically super glued on...
