Probably the switch. The switch just pulls straight out from the column. The wire that goes down into the column is another story. The best way to do it is to tie a wire to the old one and pull the wire up the column, then attach the new switch wire to the wire you pulled up through the column and then pull it back down. There is a hole on the end of the wire to put it through. If you don't do it this way, you will probably have to disassemble part of the steering column to get the new wire in.
