Derek,
There are four wires as you noted:
Horn Ground Brown w/ Black or Purple w/ Black
Turn Signal Power Green
Right Turn Signal Green w/ Yellow
Left Turn Signal Green w/ Blue
Power goes from the fuse to the horns, to the button. Pressing the
button completes the ground via the stator tube/steering box.
With the battery disconnected, you should be able to do continuity and
grounded checks of the wires in the column.
After separating the control head from the stator tube - removing the
three screws under the plate you discovered, move the turn signal switch
to the left position, center, and right position when removing the
corresponding wire, or the post that the wire is attached to will
disappear in the control head.
Cheers,
Bob Haskell
