A straight ratchet wrench like the one I have might work. I think its a fat orange wire that has to be powered up. Could also be pink or yellow. Like Scott said, ground will be black, then just try the biggest other wire first. Just be cautious applying power and only move it forward enough for access. And yes we are talking about the large electrical connector under the seat, it has enough slack that you can get to the connector once its unplugged.
