Model T Ford Forum: Forum 2013: Terminal Block Connection for Battery Horn

Hi all, I did a search for this in the forum but didn't see a definitive answer.

Looking at several of the wiring diagrams on this forum and the MTFCA wiring book, I see two different terminal locations for the horn wiring feed, terminal 1 and terminal 3. Most show terminal 1, but it looks to me like if you hook it up to terminal 1 the current draw from the horn won't show up on the ammeter. Figure 498 in my reprint of the Ford service manual shows terminal 3. Any other advantages to one location versus the other?

One other question - my car has a turn signal assembly mounted on the left hand side of the steering column, is it heresy to flip the horn button over to the right hand side of the column to get it away from the turn signal control?

Mine's on #1 and sounding the horn makes the needle jump like crazy. It's hooked up that way because I followed one of the other diagrams. I suspect #3 would work just as well.

Unless you have a show car, putting the horn button on the right is fine. Most people won't know the difference.

No. 3 terminal is before the ammeter so battery draw will not show.
No. 1 terminal is after so any current draw from the battery will show on the ammeter.

Ditto on the horn button.

Thanks for the clarification, I'll wire it up to #1. I went ahead and installed the switch on the right hand side of the column.
