Does anyone know what the electrical wire coming out of the bottom of the steering box on manual steering? It wasn't hooked up to anything so I don't know where it is suppost to hook or what it is for?

 

Well, for a '57-'60 year models, it's the Horn Wire for the Horn Button in the Steering Wheel.
It'd nice if you post What the Year of the Truck you're asking about is in the Header, mate.

 

Well if it's the 52 in your gallery, then yes it still is the horn button wire "The Colonel" mentioned.

It runs up and connects to your Horn Relay, along with power, and the wire running out to the horns.

 

Then do you connect the power and this wire together on the horn relay? Or does it go to another post on the horn relay. I think there are three connectors on the horn relay on the fender of the 52 truck. Julies you are correct on it being a 52. I don't understand how this is going to work. Wouldn't this give you a direct short. Is it a ground wire for the horns or is it suppost to go to the horn button it's self.
Thanks for the fast reply.

 

Do not connect any of the wires together on the relay. You are correct that will create a short circuit. You have a hot lead going to the relay, one wire going to the horn button, and another wire going to the horn(s) themselves. Pressing on the horn button grounds the relay, closing the circuit sending electricity to the horns, which of course, makes the honking sound.

 

One picture is worth a thousand words:

Here are your Horn Relay hook ups if it's still 6 volt positive ground.



"Hot bus" is 6 volt power. Disregard the "12 Volt..." label (12 volt and 6 volt relays are wired the same)

The horn button provides a ground for the horn relay. When it is pushed, the relay closes, and power is channeled out to the horns from the relay. The horns themselves are grounded as well.
