How do you change a power steering switch on 2005 Toyota Tacoma?

Answer 1

There might be two wires, either spade connectors or Phillips machine screw (for lugs), wiring order probably won't matter because in it's heart it is a switch driven by fluid pressure. Usually it is a 1/4" screw thread that is removed counter-clockwise with perhaps a 1/2" open end wrench. Because of the dependence on normally open or normally closed contacts inside, coupled with the fluid pressure specification, I would remove the old switch and take it to the store for them to match. at this point, the ohmmeter is your friend. If you get it wrong, the idiot light will work backwards and blind you at night as it did on my 454 Chevy, don't bother swapping wires, you will have the wrong switch.
