How do you replace a dimmer and headlight switch on a 1994 Toyota pickup?

1.Disconnect the negative cable at the battery. 2.On 1997 and later models remove the knee blocker. 3.Pull the headlight switch out to the on position. 4.Reach up under the dash panel, push the retainer button , then pull the control shaft out of the switch. the retainer button is on top of the switch component underneath the dash. Unplug the electrical connector unscrew the ferrule nut and remove the switch from the instrument panel. To install the switch, plug in the electrical connector, place the switch in position and install the ferrule nut. Insert the shaft into the switch until it is seated. I got this from the (Haynes manual chap 12-7.)
