My horn has me stumped?
Horns not working.
I tested the horns at the horn relay by grounding it and they blow - thus the relay and forward wires are good.
I am now at the connector under the dash between the turn signal switch and the connector to the dash harness.
My understanding of the horn circuitry is that when the horn is pushed, the circuit is grounded and the horn blows.
I can't figure out which wire controls the horn?
----------------------
Addtionally, does anyone have a good picure of the way the steering colum should look underneath the horn button when the horn button is removed?

It clearly shows that the horn switch grounds a 20ga black wire going to the bulkhead plug.
It also clearly shows the RH plugs transfer that line to the 20ga black wire that goes to the horn relay connector.

Problem was a loose connection under the dash between the steering column connector and the dash. harness.
Word of advice - anyone replacing their steering column wires - get the USA made turn signal replacement.
Most of the repros are made in china and seem to lack quality at the level of the connector.

For what year car? Lectric Limited, Shee-Mar Turn Signal Switches, and the "partsladi" who sells on E-bay/E-bayStores generally have USA-made reproduction switches available for mid-years. I believe that the "partsladi" and her husband were the ones who recently had the 1967 Corvette turn signal switches reproduced on the old Delco tooling.
Not sure about who to go to for C1's.
Also you can watch E-bay for NOS Delco-Remy or AC Delco switches. They come up occasionally, but prices are generally high.

I don't know where this piece of crap was made, but if you look at the area in the circle you can see that these two pieces are almost touching. Should they touch? Heck, no. Will they touch? Heck, yeah. I epoxied a piece of plastic between them so they can't touch . Bottom terminals are what it should look like.
