I have a after marker steering wheel on my 56. The car is not stock, it's more of a street rod and I believe there is a short in the steering column , the horns run constancely when hooked up. I was wondering how to hook up a horn button, either on the wheel or on the column. I see from the wiring diagram that it looks like all I need to do is run a 12 gauge wire from the button to the horn relay switch, in place of the green wire from the column, it should already be grounded, what do you guys think? All opinions appreciated. :flag6:

You don't need a heavy 12 gauge wire. Run a small wire (16 to 20 gauge) from the single wire connector with the brown wire, near the turn signal column connector, to a horn button mounted where ever you want it. Ground one side of the horn button so the button will ground the relay when pushed. ...... http://www.trifive.com/garage/56%20Chevy%20Assembly%20Manual/12-30.gif

On a 56 there should be a horn relay on the drivers inner fender near the voltage regulator. It will have 3 wires, a red wire that always has power, a black wire that goes to both horns, and a tan wire that goes to the steering column single wire connector. If you ground the tan wire to the body, the horn relay will click and blow the horns. If you ground the tan wire at the relay and it works, but doesn't work when the steering column connector is grounded, there is an open in the tan wire going inside the car. ..... http://www.trifive.com/garage/56%20Chevy%20Assembly%20Manual/12-17.gif
