you need the switch with the intermittent setting as well as the control box. the switch should be fairly easy to find new but not sure about the control unit. may have to source that used.
Go check the local junkyard, most Fords up to early 80's switches will work. Just turn the switch to the left and if they are intermittent you will know. You also have to check the wiring behind the switch and follow it to a control box under the dash. Easy peasy.
This guy has 2 for sale. I bought one from him and it plugged right in and works great. My truck isnt a daily driver but I have still used it enough to make it well worth it. All you have to do is run a ground and plug it in.
Should be a bolt in deal. Need a switch from a 73-79 and the delay control box. Check the wrecking yards or I think that some of the parts suppliers still sell the switch and control box. I swapped one in an early bronco many years ago, no big deal but if i remember right there was a six pin and a seven pin connection but they can be interchanged. Google it and also check out some of the early bronco sites as it is a popular swap for those rigs as well. I could be wrong but I think I remember reading somewhere about using a 1980-? switch as well by changing the plug on the back.
Good luck.

1973-1979 F-series and 1978-1979 Bronco Intermittant wiper switches and modules are a direct plug and play.
1980-1991 F-series and Bronco switches and modules will also work. However you have to transpose two wires that control the washer bottle pump, otherwise the washer pump will not work. Not sure which two wires though. The 1980-1991 switch and govenor (module) is still avaliable from Ford new.
If looking in the wrecking yard, even though they were avaliable on all the trim levels as an option, the Ranger XLT or Ranger Lariat, or XLT Lariat in the 80's, is most likely to have them.
I had planned on doing the intermitent wipers on my crew and supercab but had yet to look for the parts to do it. Seeing this thread reminded me to grab the switch and box out of the 86 bronco I am currently parting out. Had I not seen this it wouldn't have even crossed my mind and I would have let a part I want/need slip through my fingers.
I got mine out of a 85 F150 and put it in my 77 F250. When you unplug the wiper switch in the 77 you have two connctors, one large one in a half moon shape and a smaller one two wires ( one of the two is the black with the green tracer, Washer pump) just plug the larger one in the loom from the new switch and black box as it will go right in, and the smaller two wire one plug it in backwards (It will) and you don't have to move the pump wire. Worked in mine just as plug and play. The pull and pay yards I go to charged me 2.95 for the 86 one and later I found a 77 that had one so I took it too and put it on the shelf. The 80s switch shaft is about a 1/4" longer that the 70s but you can cut it down and grind the flat back in it if you want to. Never made any differance to me.
