The 70s aren’t exactly like the 69s, but the following should suffice. Fuse #2 is usually only used on Cougars, as they have more “stuff”. My car doesn’t use it but all you have to do is put a fuse in, and it’ll have power whenever the ignition is in Accy or On. My car even has a plug dangling there that is waiting to be used.
Wire 19A blue/red stripe coming from fuse #5 (4A) above is for the lights and is on the light switch dimmer circuit. Wires 19a through 19e go to all of those lights listed above. You could tap into one of those wires or get one of those circular clips with a male terminal on the end, that one end of the fuse 5 can clip into. You would want the right side of fuse #5 to take advantage of the fuse. Personally I would tap into the wire, solder and tape over the joint.

Yes 257 should have power. Yes connect to 257 and the other end to chassis- should be around 12vdc. Edit: with the key in Accy or ON
As previously stated, fuse 3 will be 30A with AC or 14A if heater only. If you don't have power on 257 (with key on), check both sides of fuse 3 (key on). If the inboard side of fuse 3 doesn't have power, check both sides of fuse 1 (key on). The object here is to ascertain if there is a loose wire on the back side of the fuse block. There is a remote possibility that ignition switch B to A is defective, but that runs lots of things and should be noticeable, especially on a Tach car.
FYI, fuse 2 is normally only used by Cougars, as they have more "stuff" that needs power than a Mustang.

That's spiffy Ridge!

Some of the older cars do have the system you describe, but 69s do not. Ours is simplicity itself.
Probably the easiest place to start is the blower speed resistor. Visually inspect yours to see if the resistor coils are damaged. If you have an ohmmeter you can verify its operation by connecting to the terminals- where should be obvious. If you don't have a meter, just sticking a jumper wire in the back side of the plug will give test results (as described below).
This shows the heater circuit in its simplest form as a schematic. Its good that the motor works, so finding the problem should be easier. The circuit driving the motor is identical in cars without air conditioning. Heater only cars just don't use the lower half of the schematic.
Above the red line traces the path for Low. Turn the key to Accessory or ON. You can see that it goes through both resistors in low, only the right resistor in medium, and goes directly to the motor in high. Does it work at any speed? If not the switch or fuse 3 could be bad. If it works on HI its one of the resistors or the switch. If it works on medium but not low, its the left resistor or switch. The diagram below is in the How To's section, and will tell you which resistor to jumper. This is page 2-E33 (just look for page 33). Oh, it only uses a 14 amp fuse if you only have the heater, but a 30 amp fuse if you have AC.
Turn the ignition to ON or Accy, turn the heater switch to LOW. If it doesn't work, jumper 268 red to 269 blue (that's the left resistor on the schematic). If that doesn't work, jumper 269 blue to 270 black (that's the right resistor on the schematic). If that doesn't work jump 268 red to 270 black and that will bypass both resistors.
If you still can't figure it out, tell us your symptoms.

Yeah I've been there and done that, as you know. Time helps, but more than anything, when the time is right for you, find another person to share your life with. Life can be sweet again; maybe bitter-sweet, but sweet.
I still think you should try the speed/gear calculator. If I remember correctly my ol' Vette (2001) when in OD is around 2k between 60 and 65.

Hello again, and dang I love that color. An AOD overdrive gear ratio is 0.67:1? Many people prefer a 3.5:1 rear end. Play with a calculator like this to give you an idea:

The world is surely fortunate that not everyone thinks like an engineer. Several years after my first wife's passing I went on E-Harmony and found my current wife. When she read my bio and it said I was an engineer, she immediately turned the computer off, and didn't boot it up again for two days. Her first husband was an engineer and she didn't want a repeat performance... but fortunately for me, she decided to give me a chance to prove that I was more than just an engineer ;)

Welcome to the forum. Before you reply to a post, you may want to look at the date of the last post- this one is 6 years old ;)

Raven, West Coast Classic Cougar has a variety of Cougar/Mustang parts that may fit your needs- its worth a look

Yours is different than my Mach, what attaches to this? Is the post that sticks up spring loaded or is that half of the horn contact?

Yes its correct, the Sniper instructions say the blue and green wires from the 10 pin plug go low (go negative) when turned on. These wires go to 85 which is one side of the relay coil, and 86 is the other side which goes to battery +. That operates the relay and 30 to 87 closes applying battery + to the fans, the other side of which goes to chassis.

I believe you want the US Shift Quick4 transmission control. It's about $585, and the harness is $140-160. There are lots of places that sell remaned transmissions, I had my eye on Lentech.

whe42 what are the colors on the plug to the left? BTW, the brake light switch plug is the one on the right with wires 511 Green, and 10 Green/Red
Lets see if we can further test Mid's Jedi powers
and what are these Mid? (Clock plug to the right)

I have the FMX also, but when I looked at the Gear Vendor, there wasn't an automatic mode. Do you know how they accomplish that? Something to think about is the need to make the driveshaft significantly shorter and how that affects driveline angles and vibrations.
Instead of an AOD I intend to go with a 4R70W, which is the last version of the AOD that improved all its shortcomings. It requires an electronic transmission control and, if you're handy, it is a bolt-in conversion, but the driveshaft does need to be shortened somewhat. There is a guy that makes transmission supports and a shifter mod that allows the use of the stock shifter. If you're interested I'll find his contact information.
Heres a thread on the 4R70W;

Ohhhh, its black, not gloss, not matte, maybe it was dipped? Kinda a semi-gloss.

Mine is still all original and matches the color of the plastic trim on the sides (dark charcoal or black). It has a pebbly texture and I always thought it was perhaps cardboard as there is one little spot where the side trim was rubbed it, exposing what appears to be the cardboard material underneath.

#37 feeds fuses 6 and 7, and 7 works. It sounds like the output side of fuse 6 has a bad connection in the fuse clip, or possibly the connection to wires 40 and 54.
Do you have power on fuse 5 if you turn on the light switch? This feeds a string of lights...dash, radio, heater, clock and ash tray.

You can get a crate engine from Ford that is a stroked 351 in 427 or 460, with a warranty, and it'll fit a whole lot better than a 429 that bounces off the shock towers:

In any event, you'll be needing a 9" rear end, and that sure didn't come with a 6.

Sure, everything under the sun degrades. Its electronic and susceptible to heat all sorts of things. I'm sure you'll hear people extolling the virtues and some cussing.
