I have a '66 F100 that has an after market steering wheel and I'm trying to install a horn. I am by no means an expert on wiring , so I am looking for the simplest way to install one to be able to pass inspection. Should I try to install it threw the steering wheel or create a new button by drilling a hole in the fire wall?

 

Here's my horn button. It's a floor mount, it was used for the windshield washer pump, but now it is a horn button.

 

I have the same washer button however it is on the left of my steering wheel above the ignition. The wires that run to that are cut should I buy a kit for the horn?

 

The switch on your dash was for the washer pump. You could use it for the horn but your safety inspection Guy may want to see the washers in action. Usually aftermarket wheels have an accommodation for a horn? You can wire up a horn using any push button switch,12v power source, a Bosch relay and the horn assembly. The button or switch turns on the relay and the relay connects 12v with higher amperage to work the horn. Not complicated. You will need a set of wire crimpers, some 10 gauge wire and some 18 gauge wire. The 18 gauge wire powers the switch and relay. The 10 gauge powers the horn through the relay. Position the relay and horn as close to the battery as possible.

 

Not an authority, nor familiar with what horn assembly components included in an 'aftermarket' steering wheel, as it relates to the horn button circuit?? If the turn signal switch is intact then suggest check to determine if a horn brush were to be inserted in the turn signal brush housing would it be aligned with the metal contact surface on the backside of the aftermarket steering wheel; if so, this would complete the horn circuit to the steering column collar. Finally, I would check to determine if the horn button components in the aftermarket steering wheel can be used to complete the circuit; which I think if would if the other components are aligned to that point.

The horn circuit basically, consist of a single wire; one wire from horn(s) to the horn relay, another wire from the batt. to the horn relay, and the third single wire from the relay to a 5-6 pin wire connector between the interior firewall and steering column, then from the connecter a single wire runs thru the column to the turn signal switch. If the turn signal switch is intact there's a horn contact brush 1 end of the horn brush makes contact with the single wire, and the brush side of the horn brush makes contact with a metal surface on the backside of the steering wheel. This completes the circuit from the horn to the steering column collar. Anyhow, fortunately I don't have to make sense of a long winded attempt at explaining the horn button circuit; in my view, I would first see if I could used the aftermarket horn button, it seems it would primarily be determine if the horn button in the aftermarket wheel could be used to complete the circuit to the steering column collar???

 

Does O'Reillys carry the wire and relay?

 

$9.99 Each Part Number: R209 Line: BWD


Hey Mike, this is the part number at O'Reilly's

 

Does anybody know where the horn relay might be located at??

 

my 64 is on the rt side on fender I think my 65 was on the lt side fender
find the horn and trace wire back should be yellow wire three at the relay

 

On my 65 it is on the drivers side fender in the front. You can find it very easy my finding the wire from it.

 

As jon003 mentioned; should be located next to the volt regulator.

 

I ended up finding it by the radiator.
