Hello

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.

Turn signal switch connections 1965 1966 Mustang

Once in a very great while it becomes necessary to replace the turn signal switch on a 65/66 Mustang. Once it has been determined that the switch needs to be replaced, you will discover that you have to reuse the old connectors. One is a two-wire connection that will only plug together one way. That connector is for the rear turn signals at the tail lights. If those two new wires are placed into the old connector backwards, what will happen is the right rear turn signal will start flashing when you signal a left turn. Not that big of a deal, and all that you have to do is switch those two wires around and you're all set.
The six-wire connector is sort of a different story, though. The two connectors will only plug into each other one way, but, there are all sorts of wrong ways to place the new wires into the old connector, and, if done wrong, all sorts of disasterous consequences will follow involving smoke, melting wires, etc...

Here is how those six wires are supposed to be installed in the old connector. If you look at the connector from the orientation shown in the picture, you will notice a slot in the cross piece in the center of the connector. Holding the connector so that this cross piece is pointing up and down, and with the slot closer to the top, the wires go as follows, going clock-wise beginning at the top left corner.
1)The top left corner has a yellow wire, which brings power from the headkight switch to the horns.

2)The top right corner has a white wire with a blue stripe, which goes to the front right turn signal indicator.

3)The right-side middle wire is a green/white wire which goes to the front left turn signal indicator.

4)The bottom right wire is blue/yellow, which takes power to the horns.

5)The bottom left is a blue wire, which brings power from the turn signal flasher.
6) The middle left wire is green, which brings power from the brake light switch, so that the brake lights are flashing on the appropriate side while the turn signals are flashing.

Thank you. I appreciate the diagram, have yet to see that on any of the DIY sites I've been researching in order to make this switch.
