After a couple of removals, I finally got the steering wheel installed.
First the horns wouldn't work at all. Took it off, shorted them out. One worked fine. Great. The dual horns aren't working.
Chased wires and switched them from horn to horn. Bad horn. Took it off and took out the adjusting screw and filled it with WD-40. put it back on and got it to vibrate. Cool. We've got power. Put the screw back in and, wow! Both together are loud!
Put the wheel back on, but still had to massage grounding points. After that, horn button works and we're there!
