Start by removing the steering wheel, steering wheel lock plate and lock ring, disconnect the wiring connector under the column(Long flat connector) then you can access the screws on the turn signal switch assembly and remove the switch. My suggestion is to tie a piece of wire onto the wiring connector on the bottom of the column(switch side) so when you pull out the switch and wiring you can tie the new one onto the wire and help feed the wiring down into the steering column tube.
