Hi everyone, this has been a great help to me posting on this site.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

A few questions about the horn wiring.<o></o>
<o> </o>
The wire that comes down the center of the steering column and out the end by the steering box, is this the horn wire?<o></o>
<o></o>
Next question, can anyone tell me what wires connect to what terminals on the horn relay?<o></o>
<o></o>
This will be a huge help and thank you,<o></o>

I'm not by my truck to tell you all of them right now, but I took the hood off mine today so I know that the wire that goes to the horn itself is the post closest to the passenger's side. I'll have to check on the other two (someone will probably beat me).

 

Yes, that's the horn wire.

 

Yep, that’s the horn wire but it doesn’t work the way you would think it should. So that the manufacture don’t have to run a hot wire inside the shaft, that wire grounds the horn relay to complete the circuit and blow the horn when the horn button is pushed and grounded.

Julie will be along with pictures and some real clarity soon.

 

Here's the wiring for the relay, looking at it head-on. Diagram courtesy of MTFLat, about 8 yrs ago!

 

Sure, this should help:



The "Hot Bus" is 6 volt power. With OEM wiring (6 volt Positive ground) that power comes from the "BATT" post on the Starter Solenoid. It's the same post the negative battery cable attaches to.

No change if it's 12 volt Negative Ground, you just need to make sure you use a 12 volt Horn Relay (and the "BATT" post on the starter solenoid will have the Positive Battery Cable hooked to it).

Make sure your horns are grounded really well and the ground connections are clean. I'd use 12 Gauge wire from the Solenoid and out to the horns with 6 Volt system. 12 Gauge is good if it's 12 volt. 14 AWG is too light for the truck horns.

 

Called it, lol

 

You all are the best.
Thank you so much for your help.
This is a rat rod restoration for my Father in law and
it is looking very cool.
I might be converted from a kit car guy to an old truck guy now.
Thanks again.
Mike
