Another Intermittent Wiper Question
I could not find this question addressed previously. I did search.
I wanted to see if one of you could help me with installing a intermittent wiper switch. My old '77 just had the two speed wipers. I bought a intermittent switch with the control box off eBay. My old wiper motor just had four wires coming out of it. No connector just a red, pink, black and white wire that ran directly to the switch. The switch did not have a removable connector either. It just had seven wires coming from the back of it. They are red, pink, black, white, white/blk , green/blk and orange/white.
The new switch has a connector with six wires. White, red Blk/green, blk/pink, blk/white and blue/orange. The number and the new switch starts with E9TF so I guess it came from a '89 something.
Would you know how to wire it in or should I find another switch?
Thanks!
Ted

Your switch should have a plug, not be hardwired to the governor box.
The system should be "plug-n-play" if the box is from 73-79. If the box is '80 or later there are two wires that need to be switched to make the windshield washer function.
This is what the correct governor box looks like. The red connector plugs into the switch, the black one plugs into the harness.

Thanks Mike!
I do have a switch that plugs into the red connector but I have no connector in the harness to plug the black connector into. My wiring harness ran directly into the old switch. A total of seven wires. It's all original and nothing has been spliced. There is no plug in connector to that switch. Wires (four of the seven) ran directly out of the switch and directly into the wiper motor.
I think I need to run some of the wires that ran into my old switch to some of the terminals in the black connector you are showing. Then the four wires from the motor to other terminals on that same black connector. But which wires to which terminals?
Any ideas?

Somethings not right. The harness will have two plugs that plug into either the back of the switch (non-delay) or the black connector in the picture (delay). One of the plugs go into the harness and the other goes to the wiper motor. I have never seen a switch hardwired into the harness. I looked at several different sources, Ford parts catalog, Factory service manuals and none say anything about being hardwired,
Here is a picture of the delay switch, non delay looks pretty much the same.

A picture would help us see what's going on.
The original wiring had a connector or two connectors that fit together to the wiper switch. None were hard wired.
So something is definately wrong. If the truck is original, and hasn't been tampered with, the original connector could have possibly disentergrated. Although I have never heard of that. It's also possible that you could be mistaking the connector as part of the switch.

Thanks you both for all the help! I have owned the truck since late '79 so it must be original. I currently have the entire wiring harness out of the truck with the the exception of the section that runs in the frame rail to the rear. I will look at it again.
I don't believe that I am allowed to post pics but I will check into that again and if I can I will gladly post pictures.
This is one time that I actually hope that I'm having a "senior" moment!

That's what I'm thinking.

You guys are the best and I have got to start wearing my cheaters more often! I had the intermittent switch which was already connected to the red connector. My problem was where to connect the motor wires. That connector, just as you both thought, was attached to the old switch. It just looked like part of the switch.
With your suggestion and my my glasses it all became clear! Now if the wires don't need to be switched around I'll be good to go. Thanks so much!

The intermittant wiper switch (D1OZ-17A553-A / Motorcraft SW-1010) is the same 1973/79, but there are two different intermittant wiper governors.
1973/77 F100/350 & 1971/73 Mustang/Cougar: D3TZ-17C476-A (replaced D1ZZ-17C476-A).
1978/79 F100/350 & Bronco: D8TZ-17C476-A

Your trucks wiring connector will have a White/Black stripe wire and a Green/Black stripe wire.
Where your trucks wiring connector plugs into the "E9TF" govenor module, you need to line up the Green/Black stripe wire with the Black/White stripe wire in the govenors connector where it connects with your trucks wiring.
The wires are held in the connector with little tabs that you need to gently pry on to unlock the terminals from the connector. A precision screwdriver will work well for that. I suggest moving the wire in the govenors connector that connects to your trucks wiring, rather than the one on your truck if possible.
The White/Black stripe wire will no longer be used.
Your trucks wiring uses a fuse in the panel for the wiper washer pump.
The 1980-up switch and govenor you have uses the switches internal circut breaker instead. Why you need to use the 1980-up intermitant switch as well as the govenor.
The 1978-1979 switch also uses a internal circut breaker, but utilizes the original 1973-1979 intermitant switch for intermitant wipers.
