First, lift the hood and disconnect the battery's negative wire to begin working on the switch. Take out the tilt steering column lever, then remove the screws that hold the tachometer. Then, get rid of the upper and lower shrouds on the steering column and lastly, take off the lower fixed column shroud. Unscrew the upper nuts on the steering column, but don't remove them; after that, move the upper fixed column shroud to expose the rear of the multi-function switch. Use the tamper proof Torx Bit TTXR20B2 to take the tamper proof screws off, after which you can carefully pull the switch from the column and loosen the connector's screw which will remain in the product. Take out the wire harness connector linked to the multi-function switch. You should join the wire harness connector with the multi-function switch then tighten the connector screw to 2 Nm (17 in. lbs.) for the installation process. Fix the switch in place and insert the 2 tamper proof screws to tighten them to 2 Nm. Put the upper and lower shrouds for the fixed columns back on and tighten them between 0.3 and 0.8 Nm (3 and 7 in. lbs.), then tighten the tachometer mounting screws to 3.7 Nm (33 in. lbs.). Also, place the tilt lever back onto the steering column and hook up the battery negative cable.
