1990 new to me F250 - Anyone here convert there standard two speed wipers to the optional delay wiper system?

Is the wiring the same and just a switch and wiper motor change work? Or is the harness different?

Anyone?

Thanks, David

 

80-86 you need the switch and governor box (mounts under the dash near switch and is wired
inline) and that's all, no new motor necessary.

No idea about 1990 as this is the 80-86 forum (maybe that was a typo?).

 

Opps ----- sorry my heart lies with the 80-86 trucks, but I gave up and went to the darkside after I could not find a decent 86 in this neck of the woods.

I will post properly! Mods - please delete this thread as it is posted wrongly.

I can answer your question though,.

1980-1991 F-series and bronco switches and modules are interchangeable.

Find yourself a 1980-1991 F-series or Bronco with intermitant wipers, remove the switch and the govenor box hooked to the switch and to the trucks main harness, then transplant it and hook it to your truck. Real simple upgrade and it is plug and play.

It would be better for you to find a module for a 1987-1991 truck as they were redesigned to fit into the dash better, but any module 1980-1991 will work.

Hope this helped you out.

 

I kinda figured it would work electrically, but I wasn't sure when they went to that stalk thing
from the ****.

 

It was 1992.

 

Well, if the guy has a stalk thing and wants interval wipers, wouldn't he need a stalk that
can accommodate that? Apparently, stalk wiring will plug into that governor box? This'd
be cool to know, it means I can get a governor box from 1980 up to... to... to when?

 

1991.

My '87 has a **** on the dash.

 

Whoops, I misread what you meant by stalk. I thought you were talking about the stalk mount on the govenor that raises the govenor off the dash support.

You are talking about the steering column stalk wiper switch. (duh moment) That was introduced in 1992. Funny thing the English language.

As for interchangeability: Wiper modules and switches fit the following.

1980-1983 F-100
1980-1991 F-100/F-350 and U-150 (Bronco)
1980-1999 F-600/F-900

 

I think I read that modules from some cars or newer model truck modules will work if you move one wire in the connector

 

I know this is true for 1979 and older ford pickup trucks.

You can replace the 1973-1979 govenor modules and switches with the 1980-1991 style if you move the washer pump wire in the connector.

You can also put in these modules in 1972 and older pickups as well by switching the washer pump wire.

 

continuing on i have the same 1991 truck and i get that i need the switch and module will i also need a wiper motor from that year or are they same motors.

 

The motor is the same,
Only the switch is different, and the governor module plugs between the new switch and the existing wiring harness under the dash.

 

Thanks so I am looking for a switch and module!

 

I have had issues with junkyard units not being fully functional, so you might pick up a couple switches, governors, etc...

The switch and governor in my truck now has high and low and the intermittent doesn't work right (can't adjust delay time much) and then I have another governor and switch that have low, no high, and properly-working intermittent. So you might end up mixing and matching.

Just a heads up
