Topic: Build Anomaly

My car has the horns on the passengers side with the jumper wire that came on cars with the oil cooler.  Should I leave it as is or wire it per the electrical assembly specs? 

Happy fathers day to all the fathers!

Guessing that the car in question is the car shown in your signature

- Do you have pictures of the area before you or anyone else rebuilt the car?

- Do you want to be "that guy"?

- It's nice/good that this is one of those details that you can reverse or change at any point (might need to fix a little paint to hide where it was mounted elsewhere) in the future

- If it was originally as you describe do you want to present your car with this factory mistake or build the car as it was meant to be?


Been in this situation dozens of times before and has always come down you your choice and what your willing to present to the public and be happy with. .If you leave it as is be prepared to explain to people who see it that it is not normal and for them not to copy it to their car just because you choose to

Just an opinion and set of questions and things to reflect on

Jeff, thanks.  It was on the car in my description.  I bought this car back in 79.  It was not in good shape, it was completely stock except the wheels.  I ran it for a few months and then did a partial restoration.  I removed all the rust and painted the engine compartment and radiator support with the motor out.  I remember the horn jumper with the two horns on the right side.  I didn't have a wiring diagram at that time so I put it back the same way.  I believe this was a factory mistake based on history and the fact that there was no reason to add the jumper.  I recently went through all my wiring with the ford electrical assembly specs and put everything back to spec.  I wired the horns per the drawing.  Attached is a picture of the jumper.  Alan

Does or did the car have the support bracket for the two horns (sort of inside the radiator support) on the engine side?

[alanmac]

There isn't / wasn't an additional support bracket inside the radiator support. 

[alanmac]

was the bracket a loose piece and assembled under the attaching bolts?

Thanks for the interesting information.  My jumper wire has the blue wire with a faint yellow strip.  I didn't know that the Hi and Low were specific to the mounting location.

Were there any witness marks in the correct location?

[alanmac]

I recently moved the horn to the driver side.  There is one set of marks from a serrated washer on the drivers side inside radiator support.  Paint was under the drivers side washer. The passenger side has a circular rust spot that was underneath the serrated washer.  My car has been garaged and hasn't seen rain, snow in 43 years.    Alan

There is a small dent in the hood on the passengers side where the HI horn would have been mounted.  The tab on the HI horn is worn down from the hood clearance issue.

That is odd - would expect more space between the two from the factory

[alanmac]

Jeff, Studying electrical assembly manual my horns must have been reversed at some point. They are correct now.  Hi Pitch on RH and Low Pitch on LH. There is plenty of clearance when the horns are in the correct location as per the 70 manual.  Sorry for the previous confusion.  Alan

This was a running change in late 1969 or 1970.  I think there is documentation on this in one of Anghel Restoration's write-ups.  Ford switched the horns to provide more hood clearance.

Thanks for the link. For some reason when I read the description of the one horn making contact I was still thinking one horn on each side

Will have to check my 69 Boss - don't recall the horn making contact with the hood
