Does any one know the procedure for replacing my headlight switch? Do I have to pull all the instruments? I have removed the black knob and the chrome retaining bolt and was planning to pull the switch out under the dash and rewire to the new switch one wire at a time. The switch wires seem too short to pull that way and I dont want to force it. Do I need to pull the Tach. out and if so, how do I do it? Any input would be appreciated.
