Those things really can't take much of a load at all, I blew the bridge wire on my wife's 98 just by running a tire inflator for a while while adding air to the snow tires that had been in storage. No fuses blew, just the bridge wire. I have modified tire inflators in the past to use battery alligator clips and I think in this case I will do that again, it is not that much fun to pull the middle of the dash apart to change the lighter socket.
