After I did this mod and then I tried the actual wiper kit made for the 71-73 Mustang, I had the aftermarket wiper modual fail.
So I ordered another one and had it fail also.
I ended up ordering an orignial Ford delay modual from an older Ford truck or Bronco. I already had an orignial 71-73 Ford Mustang delay wiper switch. This switch worked fantastic with the delay modual from the older Ford truck/Bronco.
The action and use of the Ford delay modual is a lot better than the aftermarket modual.
I recommend doing this if you can find a 71-73 delay wiper switch.
The modual sells for around $20.00 dollars on eBay, but you need to use a 71-73 delay wiper switch not the truck/Bronco switch.
The difference in the 71-73 wiper switches is that the delay wiper switch has a gounding wire on it and it turns to the left to slow down the wiper speed.
