Thanks Moses. I found this 5-pin relay in an (maybe) unused cooling fan relay kit I have on-hand: Picker PC792A-1C-C12S-DN-X: https://www.waytekwire.com/item/75619/Picker-PC792A-1C-C-12S-DN-X-40A-Mini/ And I believe I have some in-line 30A fuses from the old "previous owner" rats nest of a wiring harness that I can cannibalize. I'd love to find a single-speed push/pull switch that matches what I have (which may or may not be what the Jeep came with...) Is this possibly it? Looks the same as my "OEM" push-pull. https://www.willysjeepparts.com/Windshield_Wipers_c_electric.htm p/n #947341-A Since the code of my wipers ("33") isn't in the American Bosch spec sheet above, how can I verify that they are indeed single speed?

Hi Moses - thanks for the information. I'm so glad to see this site is back. Your book has been invaluable to me over the last four years through my restoration/modification project. I have the OEM American BOSCH WWF 12B33-920 motors. They came on my 1966 CJ-5A, and are wired together, to the single speed switch shown above in my earlier post. They do operate together. To be honest though as you know in our area I rarely drove the Jeep in wet weather ten years ago when it was my daily driver pre-restoration, since it's so dry in the summer in the Sierra. Per the black and white spec sheet Maury posted above, the code B33 isn't listed, but I presume these are single speed and park. Another member on EarlyCJ5.com posted this wiring diagram for the single speed wipers, which appears to be how mine were wired. This info was also posted on ECJ5 for a single-speed, 4 terminal switch: So then the question is - I do not know what the terminals on the DJ5 wiper switch are for, and to figure this out I will have to bench test them with a light bulb. I also find it interesting to note that my 1966/1967 Jeep has these single-speed electric wipers, as they were not supposed to be an option until 1968. I'm thinking that since my wipers are single speed, I might be better off going with this switch from Sam: https://stores.partsdude4x4.net/wiper-switch/

I'm about to rebuild these exact same wipers, and I'm trying to determine if they can be wired to a dual-speed wiper switch, or if I need to source a new version of the push-pull switch that was in my 1966. I have asked this question over on EarlyCJ5.com, but Moses I am wondering if you might have any insight? WillyJeepparts.com has the push-pull swtich: https://www.willysjeepparts.com/Windshield_Wipers_c_electric.htm (p/n #947341-A), but I currently have this switch from a DJ5:

Great work!
