I found that my wiper switch was bo so ordered a new one. It came and it is no good so waiting for new.
Dilemna is I bought a new 4960754 wiper motor online. It arrived and it has 2 extra terminals on front? From reading it looks like these are for a timing circuit or pulse? Attached pic of what it looks like.
My wiper motor does not have these so is there a way to fudge it or to still use this motor? It looks to have a relay and contact block that mine does not. When I try to bench test by putting 12v on center terminal and grn on lug as per Willcox testing procedure as soon as i grn the park terminal it clicks but does not run. I am missing something here. Short of removing all the extra stuff and rewiring like my old one I am at a loss.
Any help appreciated. The 4960754 numbers are the same on both.

I come up with part number 4918342 for a 1973 which is what Willcox sells for the 73.

 

The correct wiper motor for a 1973 would be 4918342. 4960754 was a replacement motor that when new did not come with a washer pump, someone must have added the wrong one.

For your testing of this motor, ditch the washer pump and then run the test as follows making sure you have the case grounded.



Here is a list of all the original wiper motor numbers.
