Slick 60's

FYI
Just had an issue with a Houston member about the delay wipers. He found an original 2-speed motor and swapped it in without issue, and bought a brand new switch from Motorcraft, but when he went to the parts depots and stores to buy a delay module, apparently that part IS NOT available anymore. Even from Ford.
We finally found one for him at my honey hole, but it took quite a while.
(And I scored another one yesterday out of a '77 F-150).
I'd say, if you're prowling the junk yards and find one, get it now. Just in case. And I'd say, get of it, including the motor, module and switch.
If you already have the upgraded switch and motor, the module is the part that plugs into the harness between the motor and switch, mounts to the bottom of the dash with one sheet metal screw, and can be added directly to your harness by just plugging it in.
There is supposed to be a "how to" for this project in the hints and tricks section so I won't go any farther here.
BTW, as far as I can tell, the later modules don't work with the older switches.
Good luck.

I know you can use the delay module from most ford trucks up to 95. I am using an 88 in Jinx and works well.

Dean.
Does it have the same plug on the back of the switch in the later models?
I thought they changed the plug when they went away from the post type switch.
Information like that is good to know.
How about the wiper motor itself?
Thanks.

And, DO NOT CUT any wires! Well, there is at least 1 and possibly 2 wires you need to cut, and only those.
One is the power supply wire to the switch - it comes off the backside of the key switch.
The other is the wire to the squirts motor - and you can often tease it out of the firewall plug.

Is there an easy way to spot a delayed wiper unit by looking at the switch or operating the switch without power?

Delay wipers have 3 positions Delay low and high. Standard switches have just 2 positions. We found several at Barclays but only pulled a couple for the guys with us that day.

Uncle, what year did the delay wipers start? and do they all inter change with the slick motor?.

Mac.
I used to think they stopped at 1978, but the guys here say the delay units continued well into the 80's.
I can't speak to that from personal experience but I believe them.
What I do know is that the 2-speed wiper motors thru '78 will bolt up to a Slick with no problems EXCEPT.........
You have to take the little arm off the shaft of your old motor and put it on the new 2-speed unit, in the same orientation as the old one that came off or the wipers won't operate properly.
My only other comment is to make sure the new wiper motor is grounded.
And, if you cut about 1/4" off the end of the switch post, your Slick knob will slide on and look bone stock.
This post started because I quit looking at the delay module itself when ever I found a wiper switch that didn't have the old style knob and post switch. Never thought the delay module itself would be in those later trucks, but I guess they are.
What I do know is that you can't buy them (the module) anywhere as aftermarket or replacement parts.
I'm collecting all I can find with the switch. The motors are available as replacement parts.

barclays had 1 less when i left.

Yes Skip, the plugs are interchangable with the different years of the switch. With the newer delays it just plugs in.

Great info guys, 'preciate it!! I'm assuming that trucks with the wiper switch in the dash are the only ones that will work for what we're doing?

If you are thinking about one on the column, you could make it work but it would not be a plug'n go situation.

Went to the junkyard today and picked up a couple of delay wiper switches and modules with the plug in harness. One was from an '80 model and the other from an 89. They both look identical but they dont look like they'll plug into my '66 harness. The switch itself looks similar but it has a squared off portion on the bottom. Does this sound familiar to anyone?

I got the 2-speed motor from a 70's truck and the delay module from an early 80's truck. I wired it together on the work-bench and made sure everything works. The diagram below is for a Mustang, but the 70's wiper motor from the truck was wired the same.

When I actually install it into my truck, I'll just have to hook up +12v, ground, and washer-pump

Do I need to get the plug that the delay harness plugged into off the truck in the salvage yard and wire it into my harness?

The delay module has two plugs on each end. They plug in between the motor and switch. The male end of the delay module plugs into the female plug on the back of the wiper switch and is identical to the plug that comes from the wiper motor. The male plug on the wiper motor plugs into the female plug on the delay module and is identical to the female plug on the wiper switch.
Don't cut any wires except maybe the little 3 pronged plug that is on the female end of the delay module where the wiper motor plugs in. That is the wiper washer switch and you can cut it close to the firewall and splice it to the washer motor. Except for the power wire coming to the wiper switch from the fuse block, don't cut anything else.

Thanks for that jm!, there`s only one thing we like more than pic`s here! and that's diagrams!, let the hunt begin!

Okay, here's a pic of what I just picked up at the salvage yard. This first pic is the switches, newer one on the left and the 66 on the right.

Here's the harness ends.

Here's the module.

Now I aint the brightes knife in the drawer but this dont look like a plug and play dealeo to me.

Heres a late 70s setup. Orange wire is power lead. Uses the late 70s wiper motor. Hope this helps.
