Damnit.  I could have retired trying to fix that mess!

You do know that MSD stands for my spark disappeared, right? Although I've never had one, and many people love them. 

I wouldn't spend a dollar for any of those three guys: they simply aren't worth restoring at all!!!

No good (concours correct) lamp sockets are available.  Be careful to find an aftermarket one with the proper diameter and length of metal before and after it snaps in place.

One other thing about most of the aftermarket wiring kits: they are basically designed for *gasp* GM products, so you'll need to cut off your Ford connectors and splice into the pigtails.
What you're looking for is more aligned with what I do: give you a factory correct set of wiring, all plug-n-play, with a 2 year warranty.  From there, you can modify things for 1 wire alternators, etc., as you see fit.

Thanks, Jay.  You'll be getting your $20 in the mail soon, so watch for it! 
Just kidding folks, but thank you for the kind words.

The two female plug has yellow/black (radio power) and blue/red (radio lamp power).
The female plug in lower part of red circle is blue/red and is for lamp power for optional clock.  The orange spliced wire is probably power for the turn signal flasher can.

1 is 4 way flasher can
2 is brake switch
3 is for optional trunk lamp
4 is for optional clock
5 is for your turn signal flashers.

If you have no voltage to center two clips (BATT) on the bottom of the fuse box, the most probable cause is that the wire going to the back side of the fuse box has broken off.  I see this about 10-15% of the time.  Disconnect the battery, remove the fuse box and inspect the two large wires where they attach to the center taps of the fuse clips on the back side of the fuse box.

You'd be better off buying the best completed car you can find given you don't have the tools/equipment to do a full restoration.  Let someone else eat the costs of restoration that almost always is never recovered when the car is sold.
The amount of funds you'll be spending to outfit a dynacorn chassis will be north of $20k.  Even so, it will not be a genuine Ford product that's 50+ years old.  A good refurbished fastback can be found (with time...) for less than the cost of the new chassis and outfitting.

A customer sent in a 69 non-tach headlight harness for refurbishment, but it was too far gone for me to repair.  The main power lines to/from the starter solenoid and alternator didn't look right to me, as the alternator line should go down into the harness quite a ways, and then gets spliced back into the main power feed.  This is the point where one of the ammeter lines gets its signal (yellow wire).  Instead, the yellow wire only was spliced into the main power feed, and the alternator line looped back and was spliced into the main power feed before going to the starter solenoid.
Whoever designed this created an epic failure of the ammeter, which now can only read discharge and never any charging.  (Not that they were all that functional anyway, but still...)
I do not know if this was an AMP harness or someone else who fabricated 69 headlight harnesses.  The next time I get a true AMP harness in, I'll tear it apart and see if they have this bad design or not.

No, 1969's did have the provision for the trunk light in the underdash, but not all tail-light harnesses contained that wire.

And it isn't found in any standard 70 harness that I am aware of; there's no connector for it in the underdash harness.  I believe you had to order a convenience package or something similar to get that line.

I would also add:
-insurance
sufficient funds in the glove compartment for bribing the local constabulary when caught speeding

No pun intended, eh?

Be thankful you're not tackling a Boss or Shelby; prices are outrageous, particularly if you want NOS!

The basic issue is that of demand: it is 100 to 1000x that of IH.  There are folks interested in concours level restorations, that drive the price of NOS stuff (what's left, that is..) through the roof.  Demand has produced reproduction parts, which range in quality to awful to good; but the cost of tooling is very high, pushing the cost of new parts upwards.  Most of the good Mustang junk yards have been picked clean, and what's left is pretty much not worth looking at, if it even exists.  Yes, there are a couple Mustang specific yards left, but the folks know of the demand for parts and the price they can get for them. 
On the other hand, there are many craftsmen who rebuild and restore things such as fuel pumps, master cylinders, brakes, power steering, and (gasp!) even wiring at fair prices.  You won't find them in the IH world, as there's too little demand for it.
It's all about supply and demand, and demand in the Mustang world dominates the market.

Sorry we don't have a diner in this forum (yet). But if you want your shorts checked, Randy ( @Midlife) will be happy to help.
