1982 and Later

See Figures 1, 2 and 3

  2.  
  3. Remove the steering wheel from the column.
  4.  
  5. Remove the turn signal assembly from the steering column. Refer to Suspension & Steering of this guide for details. It may be possible to leave the signal wiring in position and allow the switch to hang from the wires. If not, attach a piece of mechanic's wire or twine to the connector before pulling the wiring through the column. Leave the string or wire in the column so the connector may be pulled back into position during installation.

  7. It may be necessary to loosen the 2 column mounting nuts and remove the four bracket-to-mast jacket screws, then separate the bracket from the mast jacket in order to allow the connector clip on the ignition switch to be pulled out of the column assembly.

To install:
  1. Place the switch into position in the housing, then install the pivot pin.
