Hi Parkman, I had the same issue in my ongoing restoration: I wanted to use the original (vacuum) wiper switch with the electrical motor. Since parts are very hard to get here in Germany, I modified the original vacuum wiper switch to still use it with the electrical wiper motor and keep the original look.

Take a look here in my thread, there are pictures and also a small video how it works:

In fact I constructed an adapter for the backside and 3D-printed it, and the two small switches are from Amazon for around 10EUR. A few small screws and a stopper from a bike brake cable - that was the whole magic

I can send you the 3d-printfiles if you like to do it the same way, it works very good.
