Bricknose(1989) Steering Wheel onto Bullnose(1986)
Replacements I found in the hundreds of dollars and I legally need a horn, so here we are.
I happen to have a somewhat junky 1989 F350 and looking into it both the 89 and 86 had the same splines, so the only issue was the wiring.
After doing some multimeter testing, I found that the outer ring was the horn and that the left terminal in the 89 was its horn. So I just had to wire the right terminal from the 89 to ground and now I have a non-rotten steering wheel and a horn that works.

The wife likes betty boop, don't judge.
