Mr. Wilson, It is my hands on P and P experience that sez most of these switches are adaptable with minor modding. Not to argue with Ford's numbering system. It has been a few but I believe cars used the slider. They are not that hard to make work, if you want one.
IICAP I believe that is correct.

Thanks Mr. Bill, it has been several years since I was out there in the field. I was struck by how similar they ALL where when I located a Ford vehicle with delay.
Now our Escape is a different wolf, I will inadvertently hit the end of the right side stick when coming off the startup. It's the only vehicle with floor shift and the rear window wiper switch is on the end of it. Aaaarg.

Plug & play
About any 70s, 80s, 90s Ford delay that is not slide control will work. The slide control will work, just not in the original switch slot. Basically you just connect the wiring at the motor of a 2 speed motor and you are good to go. I have had it in my 66 for 15 years.

John hasn't logged on here in a few months. It is plug and play if you have a 1966 that came with 2 speed wipers using a 7 terminal wiper switch. The 6-prong connector looks sort of like a question mark (?). Not the best picture but if you have a 4-connector flat or any other style then it won't be plug and play.

Current switch new from O Reilleys
This along with pic 1-4 are all from a 78 Ford F150
Believe this was original or from my Falcon which is on the list next if I can get this CF figured out

The previous pictures were removed from a 78 Ford F150, I had everyting including wiper motor, but switch was corroded and easily replaced from O Reilleys. The wiper motor was locked up probably due to JY pull and windshield was missing so I purchased a new motor from same store, I just didn't pay attention to when I swapped out core for new and I let old one go with the harness connector. I just can't seem to fathom where the whole assy laid out on my desk is totally worthless until I can add power to circuit. Where do I install it?? I have the new ignition switch and a new headlight switch (my fuse box was rusted up) so that part of wiring I still have but there are some wires cut trying to trace them. Started to get seriously frustrated with this project just due to this stupid w/w upgrade, but he had pulled everything to do with wipers harness, motor, switch and misplaced them.

Sorry for your frustration, I'm not the wiper expert guy, but lets try some common sense thoughts here.
So you say you can power it up on your desk and it works. That means you know what terminal needs power to make it work outside the truck.
Now we need to figger the power in the truck. Should be a fuse marked "wiper", check that on both sides for power with a test light or multi-meter.
If ya got power there, look at a wiring schematic to see what color wire should be the hot line to the original wiper motor. Check that for power with switch on, if thats hot then all you need is to splice that to the terminal you used on your desk and you're done. easy peasy except any work under the dash sucks

no can't physically fire it up. Think my problem is trying to put this entire setup into a 62 F100 it was a 2 speed but I pulled the whole shebang out of a 78 F150 wiper mtr, harness, delay box, and switch. It does all plug together but I can't see where you introduce the power to the system. It is a 4 wire motor with a round 4 pin attachment I removed that and matched wires to black plug with spade terminals. Someone said to introduce the power to the red wire on the motor and it will feed from motor to switch and back. BS now got another motor and switch starting all over
