On the 'Articles' page, there is a write up about an Interval wiper mod...
I, not by any means being an electrician, wonder if this, or a similar configuration would work on the later two, or three speed wiper motors.
Anyone have any thoughts?

i havnt read the article but the intermitent boxes are just a delayed timer. you could wire to your headlights or horn if you please... its just wired in series to wutever circuit or speed...

The short answer is that that single speed intermittant wiper mod will not work for most of the 60s & 70s 2sp and 3sp Mopar wipers.

The reason is that most, if not all, 2sp & 3sp Mopar's open the park switch only when in reverse (for parking), not in forward. Some years ago, I *heavily* modified a Tiawanese delay kit from J.C.Whitney for my 2sp ("fits all models" that should have said "fits all Tiawanese models"), but it had to reverse and park each time - very, very klunky. Then I built a delay by using an externall Hall effect sensor to sense the stop position, and while it worked fine, it cost me $100 in parts and a lot of effort. I know it could have also been used for the 3sp.

The wiring for the 2sp and 3sp can be tricky; be sure you have the correct factory wiring diagram for the year and model before you try anything. Also, be aware that 3sp switches need a good ground.

In the early 80s, Mopar had some wiper motors that were designed to work with a delay; I've not looked into adopting them to earlier models.

I stuffed the dashboard switch and wiper motor from a late Diplomat into my 76 Aspen...
The switch had a delay setting/range, but it turned out that while all the components 'plugged' very cleanly, they did not 'play'; and I never pursued it any further.
-I suppose that i would have only had to run a wire or two though...
