Hello all! This is more of a question than a reply. My '75 has a very nice replacment wheel, the center badge is in excellent shape, the horns (after adjusting) work well - but pushing the badge does not honk the horns. After removing the badge, there is single wire attached that runs to the brass ring under the steering wheel and encircling the steering shaft. If I ground this wire that is attached to the badge, the horns work fine. There is no "horn brush". The drawing in the catalog doesn't help much, the service manual doesn't address and I haven't found a "tech tip". Has anyone seen other drawings or other information that would be of assistance. Thank you much!
