1. Turn your wheel over and you will find two
screws that hold a metal or plastic tab to the
wheel. This tab is used to cancel your turn
signals. Remove the two screws and the tab
(Figure 1), as you will not be needing them
with your new ididit steering column because
they are self-cancelling.
2. Begin disassembling the steering wheel.
(Figures 2-4) When taking off the screw retainer
be sure to set it down on your work bench with
the screw barrels pointing down. This will be
essential for reassembly.
3. You will need to drill a 3/8” diameter hole for
the horn cam tube to slide through. Looking
at the top center of the steering wheel, the hole
should reside 3/4” from the center of the splined
hole. Place this 3/8” hole as close to 10:30 as
possible while avoiding any existing holes.
(Figure 5 & 6) After drilling this hole, clean
the surface well to remove any grease or rust
that may have accumulated over the years.
4. The pin in the horn kit is longer than you may
need. We recommend that you install the wheel
and pin then trim the pin so that it is 1/8 – 1/4
above surface of wheel.
NOTE: After drilling
is completed you will then need to install the
spring and assembly in the horn cam as shown
(Figure 7).
5. Due to variation in wheel manufacturing there
are 2 Horn Contact Plates provided in this kit.
The smaller plate is marked with an “S” on the
back and measures approximatly 2 5/16” in
diameter. The larger plate has no markings on it
and measures approximatly 2 1/2” in diameter.
ididit recomends trying to fit the larger plate
first, but if it doesn’t fit then use the smaller
plate.
