Location: Central Ohio | On the manual gear the wire just goes up through the box and steerer tube. Not sure how the power steering wire works. I picked up a column so now I believe I have everything to convert to power steering in my 57 plymouth. |

Location: Central Ohio | OK so I had to take apart a good friends steering column apart to find the answer out for myself. Can't believe no one on here knows this? Anyway, the horn wire enters the column through the hole where the turn signal wires come in (which is what I thought). It ends in the metal turn signal switch support plate with a round plastic piece with a tiny copper wheel. There is a hole in the support plate on all cars for this. Then on the actual steering wheel, there is a copper ring that contacts the tiny wheel and that is how contact is made. This ring fits below the metal ring on the wheel that has the turn signal cancelling cam. There is a rubber washer that fits between the 2 pieces. Any power steering conversion, if you want a working horn, will need to get these pieces and the wire with the tiny wheel because they are not on manual equipped cars. |

Location: Perth Australia | Sounds like its about the same as my car then.
Been having trouble assembling a steering wheel set up as well
I got that contact ring yesterday and now I can put the wheel on without breaking the roller part

Location: Central Ohio | I think you can adjust the column a little, like move it down? Where did you find that ring? I wouldnt mind getting an NOS one myself |

It came in a box with part # 1972 250 on it
Nice box to for about a 50 year old box

| I bought it just now on the chance it'll fit my 56 Plymouth. What a ridiculous way to design a horn system. |

Location: Perth Australia | Yep
Still havnt worked out how the self cancelling bit works
I think there is supposed to be a sleeve or something goes on after the horn ring?
I havnt seen anything like that come up though

Location: Central Ohio | Yes there is a small tab on a ring that fits on the steering wheel. This is the piece that goes on over the brass ring for the horn(on power steering cars). You have to change that too, because there is a rubber washer that fits in between the 2 pieces and changes the distance the tab must be to actuate the turn signal cancelling tang on the turn signal switch assembly. The manual tab is longer because there is no washer or horn contact ring on manual cars. This power steering swap has been a pain in the butt, because I'm basically figuring it out as I go. I may post a detailed photo album of the swap when I get it all done. |

Location: Perth Australia | My car has power steering and I had a hard time trying to explain
what I needed to complete a steering wheel.
I did not know there was a difference between manual and power, so That
explains why my supplier had trouble working out what I needed.
My fault, I didnt say it was a power steer car.
Good info to know though, That means the indicator switch and everything will be different also.
Why make 2 different set ups, thats stupid

Location: Central Ohio | Supposedly, the turn signal switch is the same for manual or power. Its just the ring on the steering wheel that differs. |

Location: Perth Australia | I would have thought it was different because of the little wheel that runs on the ring
Wouldnt need it if the wire ran up the guts of the column? |

Location: Central Ohio | Nope that little wheel thingy is a separate part. As I said earlier, it fits in a little hole thats on the turn signal switch assembly. That hole is present on all cars. |

Location: Ben Lomond CA in the Santa Cruz Mtns | OK Now I really get it. Thanks. So then, are these contact wheels hard to come by? Is there a part number for it? Seems this is the only bit I'm lacking. |

Location: Perth Australia | I cant remember ever seeing one come up by itself
Most likely need to get a s/h switch assembly, be easier anyway, as the horn wire will already be included in the harness going down the column.
I would post a want in the wanted section, someone would have one, I would think also try asking Big M

Location: Ben Lomond CA in the Santa Cruz Mtns | Sent an email to John @ Big M to see if he has the parts I'm needing since I bought the other power steering parts from him. Hopefully he'll be able to pull those from the same car. |

How does the horn wire route on 58-59 power steering?
