There are a few items you may need to help you install your new ignition switch.

  • Wrench
  • Pliers
  • New ignition switch

  2. Next, remove Steering Wheel Column. Locate the steering will and remove the center column. Then you will want to disconnect the horn wires, and you should be able to remove the steering wheel. Pull the wheel with force toward you.
  3.  Disconnect Windshield/signal wiring. There are more wires that will need to be removed. Locate your windshield and signal lights wiring. Disconnect these wires. You will do this by pulling them out.
  4. Take out old ignition switch. Locate the screws holding the old ignition switch in place. Unscrew the bolt and take it and the washer out. You will then be able to pull out the ignition switch. Loosen the tabs for the switch by the wiring in the back and then pull it out.

After the cylinder is free, you will put it back in lock mode and remove the key and cylinder. Install your old key cylinder into the new ignition. You will have to make sure everything is lined up correctly or it will not fit properly. Hook all the proper wiring back into place. Make sure the screws are put back in and the steering wheel is hooked back into place; to avoid from it becoming detached while driving.
