Before letting go of the auxiliary cigarette lighter, unplug and disconnect the battery negative wire. Pull the lighter knob and lighting element out of the cigarette lighter receptacle base or just remove the plastic protective cap in the receptacle base. Measure the inside of the very bottom of the receptacle to locate the 4 rectangular retaining bosses that fasten it to the instrument panel lower bezel. Hold the tips of the external snap ring pliers against the retaining bosses, squeeze them closed to lock the bosses and then while squeezing the pliers, gently pull the receptacle base out until it's loose. First, remove the instrument panel wire harness from the main box and take out the mount from the instrument panel accessory switch. Afterward, insert the mount into the accessory switch and fasten the wire harness connector back on. Put the splines on the outside of the receptacle base connector in the matching grooves on the mount, then press until the retaining bosses click into place. Install the cigarette lighter knob and element or the protective cap and then reattach the left side of your battery.
