Wow "Thanks"  for all the help and patience Randy and Richard in helping me resolve this issue.  My head is really swimming right now.  Hopefully I'm not over thinking this.

There were no instructions that came with the new t/s switch.  I made a diagram of both connector ends wires and locations.  Also took pictures.

When I went to insert the t/s switch wires to the connector and put them back in the same sequence.  The yellow/black wire didn't match so I put it
in the only empty slot.

I will test the yellow/black on the t/s switch connector against the other wires.  If there is no readings should I then move it to the blank spot?

Do the same test using the blue wire that is in the blank spot?

Then move the blue wire from the blank spot to the left top corner spot.

Thanks Mark

That should do it.

Ok. I tested the yellow/black wire to all other wires on the t/s switch connector and no readings.

Then I tested the blue wire directly under it and got the following.

T/s lever in neutral position

Green .4, orange/blue .3, green/orange.4

Lever down position - green/white .3, green/orange .3

Lever up position - white/blue .4, orange/blue .4

Brakes - green/red .2, orange/blue .2

All other wires didn't show any reading during each test should I switch the yellow/black wire with the blue wire?

Thanks Mark

Perfect readings.  Switch the blue and yellow/black wires and you should be in business.

JACK POT!!!! Thank you, thank you, thank you.  It is so great to see turn signals blink.  Also the emergency lights flash.  I couldn't have done it without the guidance of Randy, Richard and other members.

Now to tackle the 2 new problems involving the turn signals.

1.  The t/s switch lever goes into the down position as you expect.  Pushing it to the up position is difficult.  It feels like your going to break it.  Then when it goes down to the neutral position it still blinks.  I just wiggle it a little to find the right spot then it goes off.  Any ideas on how to correct this?

2.  3 out of 4 turn signal lights work.  The right front does not blink.  I checked the bulb and looks good to go.  It is a dual type of bulb.  It is really hard to get into the socket.  The front park lamps has 2 bulbs.  The lower bulb comes on with the running lights and stays on with the headlights.  The top bulb comes on with the running lights and goes out when the headlights come on.  It also functions as the turn signal light.  So I know the bulb works when I turn on the running lights so why not the turn signal light.  Thanks Mark

1.  Can't help you here.
2. Does that bulb flash when you use the e-flasher?  Have you checked the socket tabs to ensure they are making contact with the bulb? 

With the bulb out, you can probe it with your DVM on 20VDC and see if you get the 12V on/off while turn signal is active.  If not, you have a problem with wiring up front somewhere.

If you have a generic TS switch  (not Ford) could cause the problem for fitment. Does the TS switch work normally when it is NOT screwed into the column?
The TILT COLUMN switches have that mechanism the turn stalk (chrome handle) screws into, it needs to move freely or things may bind up. Try loosening the screws if the switch is already mounted and try again. This isn't a "fix", just trying to determine what may be binding up the switch.

Another possibility is if you ever shorted out the switch with "live" current, it could be possible the switch melted internally. (I hope not, but it is possible) A little thing we "electrical/electronics people" say about how these things work is that everything electrical works on "smoke", if for any reason the "smoke" ever leaks out, it ruins them. :D PS: You do not need to witness the "smoke" for this statement to be true ;)
