My 65 F100 4wd has the two speed wipers. It also has the manual floor pump for the washer. I've been trying to determine if my wiper switch and motor will work with the later plug and play upgrade from a 79 truck. I haven't puled my switch to look at it but I understand is may be a four wire style and not have the same type of plugs as the later trucks. I haven't been able to find the 65 two speed switch on LMC, DC or Macs to compare. I've already got a delay switch, module and wiring coming so hoping it will plug into the system I have in my 65.

 

You will need a specific intermittent wiper switch and governor, but I'm not sure if your wiper motor will work.

The intermittent wiper switch is the same: 1971 Fairlane/Torino; 1973/79 F100/350; 1978/79 Bronco.

There are two intermittent wiper governors (delay modules).

1971/72 Mustang/Cougar; 1973/77 F100/350 or 1978/79 F100/350 & Bronco.

Some people say that 1980/91 F100/350 & Bronco parts will also work.

 

I put a wiper delay setup in my '69 F100 from an '87 model Ford F150.

 

Don't get confused. I got confused - I read about the incompatibility of Bosch motors, the requirement to swap the crank arm, about motors not parking correctly, etc.....
The intermittent switch/module from a Ford pu to '79 is a plug-and-play. Don't worry about what the experts with the clean fingernails say.

Thanks all. When I said my wiper switch and motor I was referring to the type of plug my switch had.

heres what I’m getting ready to install.

 

I have 2 intermittent switches with their governors. One from a 77' and one from a 78'.
I have both a 65' and 66' F-100 with 2 speed wipers. It's been a couple years since I tried this plug-n-play thing but I do remember the plugs didn't line up right.

Couple questions if I may.
Eric, you say a switch and governor from a 79'
F-100 is a plug-n-play. Is that using the 65-66
F-100s two speed wiper motor ?
According to Bill (ND), there are other years of the same type that will work. I trust his info as well as yours, since you made yours work.

I guess I'll need to re-explore this eventually but would be nice to sort out what I missed.

John, I know you don't post here much anymore but I know you have done this a couple times before. If your still monitoring, maybe you could chime in.

Yup, and it's important that you are using a two-speed motor; the single speed will not work, at least it didn't for me.
I have also heard that components later than '79 will work, including some which require modification. I think ND will know which those are.
It's a great upgrade; real easy and pretty cheap.

Thanks again guys. One other question. Does this new switch have a push feature for the washer? If so what terminal is that in the plug? My truck has the manual floor pump currently. I may stick with that but would like to know how to hook up a pump at a future date.

 

The setup you have is from an '87 (E7TF) --indentical to what I put in my truck.

I would suggest before you install it to open up the governor (black box/module) and check all the solder joints and connections on the circuit board. These modules are notorious for broken solder joints that makes some of the functions not work, like the low wiper speed and/or the delay may not function. This is why it says, "Do Not Drop" on the case. Shock induced impacts breaks joints/components inside.

Repairing bad/broken solder joints isn't difficult and almost always restores full function.










This one went in my friend's '72 F100. It checked out ok and didn't need any solder repairs. The delay setup I put in my truck had intermittent problems with the low speed and delay functions sporadically not working that required solder repairs.

Shock and vibration are the primary cause of broken solder joints/components in these modules. Particularly in the later model trucks, releasing the parking brake foot lever and letting the lever slam back against its stop is what induces shock to the module that breaks the connections. In the later trucks, these modules are located very near the parking brake lever assembly.

I set the parking brake on my '69 F100 every time I park it and get out --level ground or not. When I go to release the parking brake, I don't pull the release and just let the lever slam back. I put my foot on the lever, pull the release and let the lever up with my foot so it doesn't send a shock through the dash structure.

 

I believe you rotate the shaft to the left about 1/16th of a turn to activate the washer circuit. It's been a while since I used one, but the switch itself can be used without the delay governor and the washer feature still works, of course.

**** needs to be pushed inward.

 

Right you are. I just grabbed a D1OZ-17A553-A and it pushes in. I was mixing it with the C6TZ-17A553-B that rotates counterclockwise.

Looks like rotating this newer switch to the left is the delay amount.

Great information here. This would be an amazing upgrade for my daily driver!!! Thanks all

 

If you're retrofitting this setup in an older truck, you'll need to trim some of the wiper switch shaft length off for the ****. I trimmed about 3/8" off the stem on my wiper switch --you should always measure for your own particular application though. If the shaft is cut too short, there won't be enough stroke length when you push the **** in, to close the contacts to activate the windshield washer pump.

Yes, push to wash. I plan to connect that and use the washer button to power something else, maybe a high-beam flash. You don't really have to shorten the shaft. I planned to do that with my Dremel but it seems I've forgotten about it...
