JIm, I think by 66 the steering wheels had the slider contacts on them and certainly by 68 but the 65 didn't and I determined that the wrap and unwrap situation just wasn't going to work. I looked at Shawns 65 32Kmi Square, unmolested, and the wire goes to the coupler, across it and to the beam as does the horn wire. Whe I get up there I will stick my head under the Piglets snout as he's a 67 and see whats up with it. that horn works too.
