I had gone on a quest to get my Duster to have Delay Wipers/Pulse Wipers and be able to do it without relocating the wiper switch itself. I found it really annoying sitting in traffic, trying to run the wipers, and shift at the same time on the way home from Power Tour last year.
I had tried buying the aftermarket switch Cole-Hearsee 75600-04, but this is too big to fit in the stock location. I didn't give up, so I started thinking of vehicles that had a rotary wiper switch, but also have delay wipers.
Eventually, I found the solution, the Ford F150 prior to 1996. It is extremely popular to put the delay switch and wiper from the 1988-1991 type into earlier Ford vehicles including Broncos so I had a look at the switch and diagrams. I decided to order a used set from Ebay, it was about $80.
You can also buy a BRAND NEW one here: 69-77 Ford Bronco Wiper Delay Switch Conversion
I also bought a new wiper connector for the vehicle harness from Tom's Offroad. If you were junkyarding it yourself, you can cut this out of basically any 69-91 F150.

They did make these trucks without the pulse module, but also with 2-speed wipers. The only difference is with or without the module and the switch itself.
This is also an excellent resource for anything you want to know about this and the wiper system on those trucks, including how to fix the interval timer if need be.
Windshield Wipers
Wiring Read-across:
*Additionally there is a ground wire on the wiper switch itself. Just ground this as is convienent.
Connector Pin out for a visual, this is looking at the male terminals in the black connector on the interval timer harness:
The wiper switch for the Ford itself, you can just shorten the shaft and add a little bit more flat to the shaft so it looks like this. My stock knob fits fine, I had already modified it to have a set-screw to hold it on, I am not sure if the original retainer will hold it. The threads on the switch are the same as the OE wiper switch also. The original switch is 1.588" dia and the round part of this is 1.69". This should still fit perfect for stock gauge clusters. The switch has a ground wire with a ring terminal that you must ground.
I don't have an OE gauge cluster, but here it is installed:
Video of the wipers working. A short pulse and low and high speed:
The function of the switch is, Turn left from center: Delay timer without detents, Center detent: off, Right 1 detent: Low, Right 2 detent, high. Push=Wash.
Hope it helps all of you!
