'67 Ranger horn trim ring and signal cancelling th

My F100 is missing something in the steering column for the horn to sound and also for the turn signals to cancel. Could someone tell me what I need - a 'horn trim ring'??? Found on ebay, but don't know if it is what I need. Thanks in advance.

"Trim Ring" is usually the decorative cap/cover on the steering wheel.Sound like you need parts for,or a replacement of the turn signal switch,located beneath the wheel IN the steering column.This contains the cams that cancel the signals.
As to the horn,If you can remove the center cap from the wheel,you should find a wire or spring loaded contact on the wheel hub.Touching/shorting the wire/contact to the steering wheel nut/shaft should cause the horn to blow.Generally the cap makes this contact when pressed.If a padded wheel center there will be a pressure switch built into the pad instead.Either way there should be power at the wire/contact in the hub and shorting to ground should make horn sound.Please post back w/results.
