If you're talking about removing the wires from the nozzles, IIRC- they have a plug that plugs into the back of the nozzle, I think you have to squeeze in the 2 ears on the side of the plastic plug, then it should pull out of the nozzle.
I can check one of the parts cars tomorrow if you still can't get it with these (somewhat lame) directions.....
