need help with horn - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just bought a '67 stepside last week. The previous owner "installed" a Grant steering wheel (note quotes). The horn isn't hooked up. It works when tested, and the factory connector still exists next to the fuse box. My problem is twofold:
1. I cannot, for the life of me, figure out which wires in the steering column are supposed to end at the connector (which no longer exists) to plug into the horn wires.
2. I have no way of knowing whether the horn switch on the Grant wheel is good, or where the connection to the horn switch is made. Neither my Haynes or Chilton manuals mention the horn at all.
Please save me from a tacky aftermarket horn mounted in a place no horn should be!

Well as far as finding out the wires "fishing" i would go thru with a multi meter and find the ( O/L ) open line. wich more than likely with your horn not engaged would be it. if horn was engaged it should show either voltage or some odd amount of ohms.

after revisiting this with intent to test, every single wire that i can find goes directly to the instrument panel. i guess i need to figure out how to rewire the steering column from scratch. any suggestions? i did see the posts on stock wheels and i think i have the wheel wired right at this point. where is the connection made between horn wire (from fuse box) and wheel? that's where i'm lost.

it goes through the turn signal harness, it is connected to the brass looking button

thanks for the reply. is this piece under a metal plate that the steering wheel is screwed onto? if not, i have to track one of these down.

Yes it is in your column under the aluminum plate that the wheel bolts to, there should be a round plastic piece that is under the metal piece also. There should be an aluminum pin sticking up see the black contact, it will go through the hole in the aluminum plate.

Thanks a million times over for the pics. I don't have this part...time to start searching. Any suggestions?
