There is a very large class of people that own 65/66 Mustangs that, as far as I can tell, anyway, have been, for the most part, ignored entirely. They don't really want that 100 pt. show car that is so nice and was soooo expensive that they're afraid to drive it, they also don't want to make their car capable of achieving warp factor three. They just want this car that they dearly love to be able to cruise around smoothly and reliably, without having it dump them out on the side of the road or have it start making weird noises or belching out big clouds of funky-smelling smoke. And I think, truth be told, that this is by far the largest class of Mustang owners. They take their car to some technician when what they actually need is a mechanic, and this, frequently, does not work out very well at all for the owner. They don't want to re-engineer the entire car, they just want someone to fix what broke. These are the people that I am trying help out with this blog. Some problems require a little bit of back and forth, as in, "Try this." "I tried that and it didn't change anything."
" Oh. well, you probably need to try that." " I tried that and it helped, but it still isn't quite right." "Now you need to try this...." If you go to http://www.allfordmustangs.com/ and then go to the classics forums, you will be able to do that with a pretty hefty gathering of some very knowledgeable people that also happen to be very friendly. None of that ridiculous one-upmanship, no flaming or abuse, none of that stuff. Just good, solid advice from people that know what they are talking about.

Horn wiring for 64 1/2 Ford Mustang

Here is how the horns are wired for the Mustangs that came from the factory with a generator instead of an alternator. To see the entire diagram, just left click the part that you can see and the little bit that is hidden will pop out. You have a black wire with a yellow stripe bringing power from the hot side of the starter solenoid over to 'B' terminal on the voltage regulator. From the 'B' terminal, there is a yellow wire that goes into the horn relay, and from there goes to the underdash area, turns blue with a yellow stripe, and goes to the horn button. The 64 1/2 turn signal switch only has one horn contact, instead of the two contacts that a 65/66 switch has. When you press the horn button that grounds the blue/yellow wire, activating the horn relay. From the horn relay there are a couple of yellow wires with green stripes that go to the horns themselves. When the relay is activated, power goes from the relay to the horns, which ground out on the strut rod brackets that they are mounted on, causing the horns to honk. Nothing to it.
