This is a simple plug-n-play modification.

You need the following tools:

  • 4mm socket 7mm socket and driver
  • #20 and #30 torx bits and driver
  • Small tipped snap ring pliers for external lock ring.
  • Small screwdriver , and or hook tool.
  • 13/16 or equivalent socket, short extension and ratchet.
  • Steering wheel puller

    You will need the following parts:


  • Lower steering wheel cover
  • Control switches and harness
  • Clock spring with radio and SIR harness
  • Four 6" nylon zip wire ties

    The vehicle must be off. Set the emergency brake and observe all precautions for working on the vehicles electrical system. Disconnect the battery and use precautions for working with the vehicles air bag (SIR).

  • Start by removing the air bag module. On the back side of the steering wheel there are two slots to access the spring that retains the two module retention pins. These spring clips need to be pushed to the center to disengage from the notch. Easier said than done. I took another approach. I removed the two screws holding the rear steering wheel cover in place, using the #20 torx. This left a little room to insert a hook tool in between and release the springs.



    Carefully pull the retention clip and connector from the back of the air bag module. Place it aside in a safe place. Treat it like a bomb.


    Remove the steering wheel retention nut. Install the gear puller and pull the steering wheel. Be sure to release the horn connection. It is the white plastic piece with the two red wires.




  • Next we will work on the column. Pull the tilt knob. The small screwdriver will help get it loose. Remove two #20 torx screws from the lower half of the cover and tilt it down. The lower half attaches to the upper half with hooks at the bottom. Don't break them. Now you have access to the 4mm screw near the ignition lock cylinder that retains the upper half of the cover.You will not need to remove the upper half completely.



    Now you can remove the snap ring and the clock spring.
  • Under the dash on the drivers side, remove the black plastic panel where the OBDII connector is mounted. Remove the knee bolster. Cut the zip ties that hold the wiring in place and disconnect the yellow connector for the SIR harness.



  • Prepare the clock spring for installation. Turn the center clockwise and back two turns until yellow appears in the window. Align the horn hole and install the snapring to retain it. Route the wires down through following the path taken by the harness removed. Plug in the yellow SIR connector and the black radio control connector directly below that.

    Now assemble the steering wheel. Screw the cover to the back side. Using the #30 torx bit remove the two horn activation plate assemblies. Install the two switches and reassemble the horn plates. Place the steering wheel back on the colum lining up the arrow and index marks.

    Snap the SIR module back in place. Reinstall the nut and tighten. Plug in the airbag module and radio control connectors. Snap the SIR module back in place.

    All done. Reconnect the battery and try it out.
